Multiple logistic regression analyses of the associations between polychotomous vegetarian status and selected metabolic parameters as outcome variables.

The statistics listed in each cell are the estimated adjusted odds ratio, (95% confidence interval of adjusted odds ratio), and (p value) respectively.MNCEP MetS = modified national cholesterol education program criteria of the metabolic syndrome, IDF MetS = International Diabetes Federation criteria of the metabolic syndrome; non-VEG = non-vegetarian.Vegetarian duration n of non-vegetarians = 315, n of ovo-lacto-vegetarians of 1–11 years = 215, n of ovo-lacto-vegetarians ≥ 11 years = 154, and n of pure vegetarian = 22 respectively.The vegetarian status includes 4 mutually exclusive categories, non-vegetarian, ovo-lacto-vegetarian for 1–11 years, ovo-lacto-vegetarian for ≥11 years, and pure vegetarian, which was defined by three dummy variables with non-vegetarian as the reference category.HL GOF test: Hosmer-Lemeshow goodness-of-fit test, where p value > 0.05 indicated a good fit of logistic regression model to data.AUC: Area under receiver operating characteristic curve. AUC of 0.7 and above is considered acceptable discrimination.
