Statistical Analysis
REGRESSION, SESSION, SECONDARY
Session 1 data were stored in REDCap, whereas session 2 data were stored in the SQL databases. Data were imported into the statistical software R (R Foundation for Statistical Computing) for the analysis. Descriptive statistics, including mean, SD, frequency, percentage, and IQR (25th percentile and 75th percentile) were obtained. ANOVA and Fisher exact test were used to examine the variation of variables across groups. Linear regression analysis was used to compare CPT (primary outcome) and CDS adoption rate (secondary outcome) between the tailored CDS group and the 3 nontailored CDS groups and to examine their association with various predictors. For the handling of the small amount (<1%) of missing data, we used the approach of multiple imputations, where multiple completed data sets were generated using the fully conditional specification. Inference was performed on each completed data set and then aggregated using the Rubin rule [
