Statistical Analysis
The analysis was done using a set of steps. In Step 1, we described the baseline characteristics of the participants and conducted a comparison between the intervention and the control groups (for all study participants and for the ones that did not come back during the study period) using independent t-test for continuous variables and Chi-square test for categorical variables. In Step 2, we calculated relative risk reduction; and finally, in Step 3, we conducted Kaplan-Meier survival analysis to further contrast the difference in the proportion of defaulters between the intervention and comparison groups, using the outcome of coming back to the clinic appointment during the study period. All data analysis was carried using Stata/MP 14.0.
