Multivariate logistic regression and trend test were used to analyze the association between the FMT and the prevalence of gallstones. 1No covariates were adjusted. 2Sex, age, race were adjusted. 3Sex, age, race, education level, marital status, PIR, BMI, physical activity level, alcohol use, smoking status, diabetes status, hypertension status, energy level, protein intake, carbohydrate intake, dietary fiber intake, total fat intake, total saturated fatty acid intake, and cholesterol intake were adjusted. FMT, first meal time; PIR, ratio of family income to poverty.
