aInconsistency categories are combined for each drinking measure as similar patterns were found in most cases.
bTotals differ due to missing data and eight participants for whom the two surveys were not completed in the same day.
cTrend P-values indicate the significance of a score test for linear trend of log odds; all other P-values indicate the statistical significance of each association using the likelihood ratio (LR) chi-square test.
dHDO analyses included current drinkers (i.e. 446 men and 430 women who reported past-year alcohol consumption on at least one instrument).
Bold values represents the associations that were statistically significant (P < 0.05).
