Study Design. The goal of this study was to investigate the association between peer status and friendship quality and the mediating role of empathy and prosocial behavior in this association. Because friendship is a dyadic concept involving two friends our study employed a dyadic design using information from both friends. Accordingly, we used the Actor Partner Interdependence Model (APIM) for the analysis of dyadic data (Xxxxx & Xxxxx, 2000; Xxxxx & Acitelli, 2001; Xxxxx, Xxxxxxxx, Xxxxxx, Xxxx, & Xxxxx, 2002). The APIM includes two types of effects. The actor effect (path a in Figure 1) is the effect of adolescents’ peer status on their own friendship quality rat- ings. The partner effect (path p) is the effect of adolescents’ peer status on their friends’ friendship quality ratings. For example, popular adolescents might rate the quality of their own friendships highly (actor effect), and their friends also might rate the quality of their friendship highly (partner effect). The APIM simultaneously estimates the coefficients for all paths, with the two paths a and two paths b in Figure 1 set equal due to indistinguishabil- ity of dyad members (mutual friends) in this study. An extension of this model is the Actor–Partner Interdependence Mediation Model (APIMeM) (Xxxxxxxxx, Xxxxx, & Xxxxx, 2011). The APIMeM allows for testing of mediation effects within the actor and partner paths. While the APIM is a technique to examine associations between the characteristics of the two members of a dyad, it does not explain why these associations occur. With two members in a dyad, characteristics of both dyad members can be (partly) responsible for existing actor and partner effects. Using APIMeM, it is possible to differentiate between actor mediators and partner mediators on either actor or partner paths. Figure 2 shows the resulting four different mediation paths: actor–actor (aA1–bA1 and aA2–bA2), partner–partner (aP1–bP2 and aP2–bP1), actor–partner (aA1–bP2 and aA2–bP1), and partner–actor (aP1–bA1 and aP2–bA2) mediation. For example: the link between friend A’s peer status and friend A’s friendship perception may be explained by their own prosocial behavior (actor–actor mediation). This link also may be explained by friend B’s prosocial behavior (partner–partner mediation). The link between an friend A’s peer status and FIGURE 1 The actor-partner interdependence model (Xxxxx & Acitelli, 2001) friend B’s friendship perception similarly may be explained by friend A’s prosocial behavior (act...
Study Design. This is a randomized, multicenter (n=11), open-label, parallel group, controlled research study to demonstrate that mucous fistula refeeding between enterostomy creation and enterostomy closure reduces the time to full enteral feeds after enterostomy closure compared to standard of care.

Study Design. The study is based on a literature review conducted by UW Precision Forestry Cooperative (PFC) for RSAG in 2015 to identify and compare the suitability of remote sensing techniques for mapping riparian forest structural characteristics and composition (i.e., riparian forest metrics): Xxxxxx, X. X. and X. Xxxxx, 2015. Feasibility of applying remote sensing to a riparian stand conditions assessment, Agreement No. IAA 15-118 (Revised 1/1/2015); Prepared for Washington Department of Natural Resources. The review findings were used in refining the focus on types of remote sensing data and their suitability for assessing riparian metrics and lead to the decision of which metric analysis would be feasible to undertake as a pilot to explore the feasibility and relative benefits of using optical and LiDAR remote sensing in the state of Washington.
Study Design. The Phase 3 study will be a randomized, double-blind, multicenter, placebo-controlled trial covering 1 [*] of observation, followed by randomization of qualified subjects to [*] months of treatment and a 1 [*] safety follow-up period. Two doses of ER 206323 will be studied. Patients will be postmenopausal women defined as being 45 years old or greater and having [*] months of spontaneous amenorrhea, or [*] months of spontaneous amenorrhea with serum FSH levels of > [*] IU/L, or as women who are [*]-weeks post-surgical oophorectomy. As for the Phase 2 study, hot flash frequency and severity will be established during a pretreatment period of observation and qualifying patients will be then eligible to enroll in the study. As before, the criterion for entry will be a frequency of [*]hot flashes per day or [*] to [*] hot flashes per [*]. Efficacy will be assessed as the reduction in frequency and severity of hot flashes compared to placebo. The estimated subject number and dose groups are outlined below: * Confidential Treatment Requested by the Registrant. Redacted Portion Filed Separately with the Commission.

Since [*]doses of ER-306323 will be administered in this trial, there will be at least [*] patients available to provide endometrial safety data on this product. While powered beyond this need, the Phase 3 study will provide confirmatory evidence of efficacy for ER-306323. The [*] doses to be employed in the Phase 3 trial will include the [*] as identified in the Phase 2 study as well as [*] provide [*]. Efficacy will be based on difference in efficacy [*]. Endometrial safety will be based on self-reported vaginal bleeding, endometrial ultrasound and endometrial biopsy data. Endometrial biopsy data will be assessed according to objective common criteria by a panel of [*]pathologists in [*] independent medical institutions. The Phase 3 study will provide additional long-term safety information on serum lipids and on coagulation markers such as [*]. Influence of ethnicity on efficacy and safety will be assessed and drug-drug interaction effects will also be evaluated where appropriate.

Study Design. The scientific and implementation design of the Study are at the direction of the PI. Participation in the Study does not grant the School the opportunity to modify or change the design of the Study in any way, except as otherwise noted in this document or where the Study design is purposefully left to the School to determine (such as with the Custom Questions). Additional information regarding the Study Methodology and the implementation of the Study is set forth in Exhibit A.
Study Design. The study is a multicentre, two-arm, randomised, double-blind clinical trial, using temozolomide as an active comparator. Following completion of radiotherapy treatment according to the ‘Xxxxx regimen’, subjects will be assigned to one of two treatment groups, in a 1:1 ratio. The first group will receive temozolomide, in accordance with the labelled dose and schedule. The second group will receive GDC-0084 at a dose of 45mg, once daily.
Study Design. As described in Section 1 of the Aging Study Proposal.
Study Design. The main aim of this project was to investigate the relationship between AC and BMD in postmenopausal women. The study was divided into three parts:
Study Design. In this multicentre study, we asked physicians from seven Dutch hospitals to complete a questionnaire after each consultation with a unique eligible patient, between June 2018 and December 2019. Participating patients were asked to complete a questionnaire after the consultation, and again 1-2 weeks later. We aimed for 50 physicians, each including at least two patients, based on the COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) checklist.18-20 The Medical Ethical Committee of the Leiden University Medical Centre (LUMC) approved the study (NL50551.058.14, P14.207), which was conducted according to the Dutch Medical Research Involving Human Subjects Act.
