Bold font indicates a statistically significant p value.
*p Values were calculated from the Fisher’s exact test for the categorical variables by quartiles of alcohol intake and analysis of variance for the continuous variable (ie, age) by quartiles of alcohol intake. All p values are two sided.
†Alcohol intake was categorised by the quartile intake values among human papillomavirus (HPV)-negative men.
