T2DM, type 2 diabetes mellitus.

^*Crude: unadjusted.

^†Model 1: adjusted for age, region, gender, education level, marital status and per capita monthly income.

^‡Model 2: further adjusted for BMI, smoking, alcohol drinking, physical activity and family history of diabetes based on model 1.

^§Model 3: further adjusted for energy based on model 2.

^‖Factor scores were divided into quartiles.

^¶For the quintiles of each dietary pattern, the first quintile (Q1) was considered as the reference group.

^**Factor 1, ‘meat’ pattern.

^††Factor 2, ‘grains-nuts-egg’ dietary pattern.

^‡‡Factor 3, ‘vegetables-staple-fruits’ pattern.
