a
Abstinence is defined as a patient reporting no drinking in the past 30 days.
b
% reporting abstinence of relapse = nreporting abstinence ÷ ntotal reports; % reporting relapse = 100 − % reporting abstinence
c
Odds of abstinence = nreporting abstinence ÷ nreporting relapse; OR = oddsA-CHESS ÷ oddsControl
d
P values calculated using Fisher’s exact test
e
Reported abstinence at all three time points (months 4, 8, and 12)
