Subjects were assessed on CIWA-Ar for severity of alcoholwithdrawal at baseline. CIWA-Ar scale is a validated 10-itemassessment tool with high inter-rater reliability and constructvalidity (Sullivan et al., 1989). Our scoring of subsequentCIWA-Ar ratings was as follows: (a) CIWA-Ar >15; SevereWithdrawal, CIWA-Ar to be applied 2 hourly till the scorecomes below 15, (b) CIWA-Ar 8–15; Moderate Withdrawal,CIWA-Ar to be applied 6 hourly till the score comes below 8,(c) CIWA-Ar <8; Mild Withdrawal, CIWA-Ar to be applied 8hourly and (d) Stop CIWA-Ar assessment when the score is<8 for three consecutive readings (viz: Mayo-Smith, 1997;Asplund et al., 2004; Mee-Lee, 2005).
