Note. FM = factory-made cigarettes; GEE = generalized estimated equation; RYO = roll-your-own cigarettes. All figures in the table are odds ratios adjusted for age, sex, cohort, urban/rural, income, education, ethnicity, smoking frequency, and cigarettes smoked per day.
*p < .05; **p < .01; ***p < .001; p values were adjusted for multiple comparisons using the Benjamini–Hochberg method to control the false discovery rate.
