Notes: Calculation based on INPC data January 1, 2012- July 6, 2019; unit of observation is the individual patient; all event-study regression estimates control for individual fixed effects, fixed effect for the period in which POINT was in effect (after February 2016), demographic controls and patient-level exposure to treatment, proxied by duration of the pre- and post- period for each patient. Estimates presented are marginal effects, standard errors are presented in parenthesis;

amodeled using individual fixed-effect negative binomial regression;

bmodeled using a fixed-effect logistic regression.
