Note: The data include 96,964 clinician-patient-task level observations. Results derived from Multi-level logit model with random effects at the patient and clinician level. Marginal Effects (percentage point increase compared to the omitted baseline) reported.

Impact for gift, delayed gift and prize are additional effects over the trend for all groups and impact for the control group is equal to the trend for all treatments Standard errors in parentheses: significance at 1% (***), 5% (**), 10% (*). Period 1 refers to data collected after the encouragement visit. Period 2 refers to data collected after the follow-up visit. Coefficients are from a single regression.
