aDay −30 scores were derived via recall during first (day 0) interview and are used as baseline QALY scores when QALYs are calculated for participants when they served as their own controls. Skewness and kurtosis tests indicate we cannot reject that the adjusted mean scores are distributed normally.
bDifferences between the day −30 score and the day 0, 7, 15, 30, 90, 180, and 365 scores are statistically significant, P < .0001, for each of the 7 unadjusted and adjusted contrasts.
