就胆结石与饮食、饮酒及相对体重的关系进行了一项病例对照研究。研究对象包括267名最近被诊断为胆结石的住院患者、241名从社区挑选的分别配列的对照者及359名从住院患者中选出的对照者。为了判断个体营养与胆结石形成之间的基本关系,进行了复杂的逻辑回归分析。 A case-control study was conducted on the relationship between gallstones and diet, alcohol consumption, and relative body weight. Participants included 267 hospitalized patients who were recently diagnosed with gallstones, 241 individually assigned controls selected from the community, and 359 controls selected from hospitalized patients. In order to determine the basic relationship between individual nutrition and gallstone formation, a complex logistic regression analysis was performed.
