Differences are calculated as 1st group - 2nd group, where pairs are expressed as “1st group vs. 2nd group”.
Note: ATE weighted estimates represent estimated abstinence rates if the whole population received the corresponding treatments. ATT weighted estimates represent estimated abstinence rates if the matched population received the corresponding treatments.
