^aData from Qatar Biobank. Values are odds ratios and 95% confidence intervals. Three dietary patterns were derived from factor analysis based on Scree plot, eigenvalues >1, and interpretability of dietary factors.

^bSignificance in logistic regression. Dietary pattern scores were used as continuous variable.

^cAdjusted for age (continuous), gender, smoking, education, leisure time physical activity, and BMI (continuous).
