Figure. 1.

Total testosterone level and prevalence of testosterone deficiency according to alcohol consumption in flushers and non-flushers. (A) One drink was equivalent to 14 g alcohol. Values are presented as the mean±standard deviation. ^*P=0.040 compared to non-drinkers; ^†P=0.023 compared to flushers who had eight or fewer drinks per week by analysis of variance with the Bonferroni post-hoc test. (B) Testosterone deficiency was defined as <3.5 ng/mL. Values are presented as numbers (%). Five groups were analyzed using the chi-square test (P=0.026), and the differences among the five groups were analyzed using the Bonferroni post-hoc test. ^‡These values were significantly different compared to the others (P=0.05) in the Bonferroni post-hoc test.
