Baseline SSD was assessed via Timeline Followback (TLFB) method for the period of 56 days prior to the baseline visit. Total drinks for 56 days were summed and divided by 8 weeks for a SSD per week variable.
b

c
9-month SSD was calculated using date from the 9-month post-baseline visit. Sum of total drinks consumed since the 6-month visit were divided by number of weeks in the assessment period (usually about 12).
