Indicator variables of attrition (loss to follow-up at main end-line study) regressed on treatment arm with robust SEs clustered by village in parentheses are shown. The excluded groups in the first regression are both control groups, and the appropriate single control group is excluded in the second and third specifications. F statistic indicates the test of all indicators equaling zero.
