We define an after intervention dummy variable to be equal to one for the data points of IPT, month 3, and month 6 surveys, and equal to zero for the baseline. Separate dummy variables for different surveys were also fitted, and the estimated coefficients are not significantly different for different surveys, so the after intervention dummy variable is included in the final model
