Secondary Logistic Regression Clause Samples
Secondary Logistic Regression. I further limited the study sample to those reported having no documented difficulties in functionality at baseline and conducted a secondary logistic regression (sample sizes for measuring ADL and IADL are 1,012 observations and 744 observations, respectively) using the sub-sample. The weighted marginal effects of patient COC and other confounders at baseline from the main logistic regression are presented in Table 5: Effects of Patient COC on Functional Decline Within One Year among Patients with No Reported Functional Difficulties at Baseline, and the statistics presented in the table are the percentage effect on the dependent variable. When examining the outcome measure of functional decline in ADL, compared to low level of COC, medium level of COC is associated with a 7.51% (p < 0.05) lower incidence of experiencing functional decline in the subsequent year, after controlling for other confounders at baseline. However, the results didn’t show a statistically significant impact of high level of COC on experiencing functional decline in the subsequent year, compared to low level of COC. Among the older adults with ADRD, the oldest old are more likely to experience functional decline – comparing to older patients in the age range of 65-69, 85-89-year-old and 90-and-older are 32.0% and 34.7% more likely to experience functional decline, respectively. The impact of older age is magnified when limiting the study sample to those without functional difficulties at baseline. Currently smoking status and obesity are associated with 8.28% and 8.24% higher incidence of experiencing functional decline among older adults with ADRD. When the outcome measure of functional decline is evaluated through IADL, I didn’t find a statistically effect of COC at baseline on functional decline in the subsequent year. However, the involvement of PCP in a patient’s E&M visits is associated with 25.8% lower incidence of experiencing functional decline in the subsequent year.
