Coffee consumption and cholecystectomy were reported by participants on biennial mailed questionnaires. RESULTS: During 20 years of follow-up to the year 2000, 7,811 women reported a cholecystectomy. Compared with women who consistently reported consuming no caffeinated coffee, the multivariate relative risks (***adjusting*** for risk factors for gallstone disease) of cholecystectomy comparing increasing categories of consistent intake of caffeinated coffee (0, 1, 2-3, and > or =4 cups/day) were 1.0, 0.91, 0.78, and 0.72 (95% confidence interval comparing extreme categories, 0.62-0.84; P value of test for trend < 0.0001).
