*
Rheumatoid arthritis risks across tertiles of E-DII and HEI-2015 scores were calculated using binary logistic regression models.
†
Model 1 was adjusted for continuous covariates, including age, BMI, waist circumference, physical activity and sleep duration; model 2 was further adjusted for categorical covariates, including gender, smoking, education, dietary supplementation and family history of rheumatoid arthritis.
