采用病例对照研究及Ｌｏｇｉｓｔｉｃ回归模型对有关饮食因素进行了分析。单因素分析提示脑胶质瘤的发生与胡萝卜、萝卜、西红柿、大蒜、苹果、桔子、梨呈负关联；与咸鱼、酱、咸菜、酸菜呈正关联。多因素分析发现胡萝卜、桔子、西红柿、苹果是脑胶质瘤的保护因素；酱与酸菜是脑胶质瘤的危险因素 Case-control studies and Logistic regression models were used to analyze dietary factors. Univariate analysis suggested that the occurrence of glioma was negatively correlated with carrots, radishes, tomatoes, garlic, apples, oranges, and pears; it was positively associated with salted fish, sauces, pickles, and sauerkraut. Multivariate analysis found that carrots, oranges, tomatoes, and apples are protective factors for gliomas; sauce and sauerkraut are risk factors for gliomas
