↵*This includes all current drinkers who reported weekly alcohol units of >50 units for men and >35 units for women.
↵†The P value (two-sided) is from the likelihood ratio test for heterogeneity in the probability of consuming harmful weekly amounts of alcohol, across different levels of the specified explanatory factor with adjustment for all other factors in the multivariable model, using only the current drinkers. The threshold for statistical significance was 0.01.
↵‡The Ptrend is from the test for trend and the P value in parentheses is from the test for departure from a linear trend. Both P values are two-sided. The threshold for statistical significance was 0.01.
↵§This is not all current drinkers (n = 8,024) due to missing alcohol units for 51 survivors.
↵∥These values do not equal the total because of unusable or missing data (legal marital status: missing data, n = 174; educational attainment: missing data, n = 188).
