^aCoefficient from linear regression model indicates difference in relative abundance of genera in women relative to men and in ever smokers relative to never smokers, adjusting for sex, age, BMI, smoking, and education (sex or smoking was not adjusted for in its respective main analyses).

^bP values were corrected for multiple testing using the Benjamini-Hochberg procedure to control false discovery rate (FDR) ≤ 5%.
