Figure 4.

Alcohol consumption, flushing reaction, and odds ratios (ORs) for each LVL group adjusted for sex and age. Panels A, B, and C show the relationship between alcohol drinking and the LVL grade as per flushing reaction. The white boxes and black circles show the sex- and age-adjusted ORs of exhibiting the LVL for light (1–8.9 units/wk), moderate (9–17.9 units/wk), or heavy alcohol drinkers (≥18 units/wk) and for ex-drinkers in the patients with no-flushing and flushing reactions, respectively; the vertical lines show the 95% CIs; the black triangle shows the reference category who are nondrinkers regardless of flushing reaction. The asterisk (∗) indicates a statistically significant difference in OR between the patients with no-flushing reaction and those with flushing reactions in the same category of alcohol consumption.
