We compared patient exploratory outcomes using the above statistical tests. For physician exploratory outcomes, we described prestudy and poststudy results in the intervention and control groups. To explore how the intervention’s effect on primary and secondary patient outcomes varied by relevant subgroups, we stratified analyses by physician gender, years with PCP, and patient health care preferences.We used multiple imputation to impute outcomes and years with PCP (postsurvey variable) for patients who did not complete the poststudy survey. Specifically, we used predictive mean matching with a fully conditional specification (robust to nonnormality of outcomes). We used R statistical software (version 4.2.2) and considered 2-sided
