The data safety monitoring board (DSMB) will analyze a proxy endpoint, in-hospital mortality, for subject safety. The stopping guidelines are defined as follows: The primary endpoint will be analyzed for safety reasons if a difference in in-hospital mortality of >6% is found with a p-value <0.005 (Chi square test). The study will only be stopped early for safety reasons if a difference in primary endpoint (28-day mortality) is found of >6% with a p-value of <0.001. Subgroup-analyses are planned to investigate the effects of oxygenation targets on the primary endpoint in the following subgroups: ARDS at ICU admission, patients with sepsis as reason for admission, patients with stroke, patients with myocardial infarction and patients with elevated plasma lactate (> 2 mmol/l). Analysis will primarily be performed following the intention to treat principle. To handle protocol non-adherence a secondary per protocol analysis will be performed. No or minimal losses to follow-up for the primary outcome is anticipated. Complete- case analysis will be carried out for all the outcomes. However, if more than 5% of missing data is found for the primary outcome, a sensitivity analysis using multiple imputations will be carried out. OVERSIGHT AND MONITORING The coordinating center and steering committee will provide trial oversight and is composed of the principal investigator, leading investigators and experts of ventilation who contributed to the design and revision of the study protocol. The leading investigators are responsible for the daily management of the trial and provide assistance to participating ICUs in training in study related procedures for the local staff, trial management, data management and monitoring. Local investigators in each site will screen the patients who require mechanical ventilation and check if they are eligible for participation, perform randomization, supervise data collection and ensure adherence to the ICH-GCP guidelines during the trial. An independent Data Safety and Monitoring Board (DSMB) watches over the ethics of conducting the study in accordance with the Declaration of Helsinki, monitors safety parameters and the overall conduct of the study. The DSMB is composed of three independent individuals. The DSMB will meet at least yearly. No competing interests were reported by the DSMB. Adverse events (AE) are defined as any undesirable experience occurring to a subject during the study, whether or not considered related to the trial procedure and intervention strategies. Since this is a low-risk study in critically ill patients, comparing two currently used PaO2 targets, additional undesirable events related to the study protocol are not anticipated. Therefore, we will only register serious adverse events (SAEs) and will not record AEs. Because this is a study in critically ill patients, SAEs are expected to occur frequently. Therefore, the following SAEs are not considered untoward in this population and will not be treated as SAE: \u2022 Death not related to the study intervention \u2022 Infections \u2022 Bleeding \u2022 Organ Failure The following events occurring during ICU admission will be treated and registered as SAE: \u2022 PaO2 \u2264 5 kPa (37.5 mmHg) \u2022 Ischemic events (limbs, cerebral, myocardial, intestinal) \u2022 In hospital cardiac arrest (IHCA) \u2022 SpO2 <80% for longer than 10 minutes (not explained by technical failure) \u2022 Death possibly related to the study intervention The site investigator will report all SAEs to the leading investigator without undue delay after obtaining knowledge of the events. The sponsor or lead investigator will report the SAEs through the web portal to the accredited ethical reviewing board that approved the protocol, within 7 days of first knowledge for SAEs that result in death or are life threatening followed by a period of maximum of 8 days to complete the initial preliminary report. All other SAEs will be reported within a period of maximum 15 days after the sponsor has first knowledge of the serious adverse events. On-site monitoring will comprise controlling presence and completeness of the research files and the informed consent forms, source data checks will be performed as described in the monitoring plan. Every participating center will be visited at least once every year. Monitoring in the Leiden University Medical Center, the coordinating site, will be executed by internal monitors of the LUMC according to the monitor plan. Independent monitoring of participating sites will be arranged by the coordinating investigator and principal investigator. A substantial amendment is defined as an amendment to the terms of the ethical reviewing board application, or to the protocol or any other supporting documentation, that is likely to affect to a significant degree: - the safety or physical or mental integrity of the subjects of the trial; - the scientific value of the trial; - the conduct or management of the trial; or - the quality or safety of any intervention used in the trial. All substantial amendments will be notified to the ethical reviewing board and to the competent authority. The study protocol and analysis plan will be published before start of the study on \u2587\u2587\u2587\u2587\u2587\u2587\u2587\u2587\u2587\u2587\u2587\u2587\u2587.\u2587\u2587 (trial number: 7376). The results of the study will be presented to (inter\u2013) national scientific journals, professional societies and guideline committees. We will submit analyses to scientific journals in the field of Intensive Care medicine as well as anesthesiology, since both ICU physicians and anesthesiologists apply ventilation in the ICU setting. The results of this study will be disclosed unreservedly according to the Central Committee on Research Involving Human Subjects (CCMO) statement on publication policy (\u2587\u2587\u2587\u2587://\u2587\u2587\u2587.\u2587\u2587\u2587\u2587.\u2587\u2587/attachments/files/ccmo-statement- publicatiebeleid-3-02-en.pdf). Material for public dissemination will be submitted to the sponsor for review prior to submission for publication. Each study site will provide one co-author, when at least ten subjects have been included. If more than one hundred subjects have been included or reasonable efforts have been made to reach this number the study site will provide two co-authors. The co-authors will be determined in accordance with general accepted academic standards for authorship. Prior to submission co-authors will look through the manuscript.

The DSMB will review the incidences and circumstances of adverse events that occur during the course of the trial. Formal interim analyses will occur after 25%, 50%, and 75% of patients have been enrolled. The objectives of the DSMB are ordered as follows:\n1. To monitor the safety of the study subjects.\n2. To recommend stopping the trial due to futility.\n3. To recommend stopping the trial due to overwhelming efficacy. An efficacy interim analysis will test the null hypothesis that the distribution of scores on the modified \u2587\u2587\u2587\u2587\u2587\u2587 Scale at Day 90 is identical in the magnesium sulfate and placebo groups versus the one-sided alternative that the distribution of scores is shifted lower in the active magnesium sulfate therapy group. This test will be performed at the 1% alpha level at each interim analysis. This is the same null hypothesis employed in the final primary trial efficacy analysis (evaluating whether patients are benefitted by treatment with magnesium sulfate), and will enter into the Lan and DeMets spending function. A safety interim analysis will test the null hypothesis that the distribution of scores on the modified \u2587\u2587\u2587\u2587\u2587\u2587 Scale at Day 90 is identical in the magnesium sulfate and placebo groups versus the one-sided alternative that the distribution of scores is shifted lower in the control placebo therapy group. This test will be performed at the 1% alpha level at each interim analysis. This analysis will be conducted to ensure that patients are not being harmed by assignment to the magnesium sulfate group during the course of the trial. As this pure safety, one-sided analysis does not overlap with the final efficacy analysis (evaluating whether patients are benefitted by treatment with magnesium sulfate), it will not enter into the Lan-DeMets spending function. Futility analysis will be conducted at the three interim analyses, calculating the conditional probability of a positive result on the primary efficacy outcome based on the observed treatment effect in the the data collected to that point.
