Values are RRs (95% CIs), estimated through robust-error-term Poisson regression models. DII, Dietary Inflammatory Index; T, tertile.
P for trend.
At least six 24-h records: n = 2445. T1: n = 815; T2: n = 815; T3: n = 815.
Model 1 is adjusted for sex, supplementation group (except in analyses stratified according to supplementation group), age, follow-up duration.
Model 2 is adjusted as for Model 1 + number of 24-h records, daily energy intake, education level, occupational status, living arrangement, smoking status, and physical activity.
Model 3 is adjusted as for Model 2 + BMI.
Placebo group: n = 1313. T1: n = 437; T2: n = 438; T3: n = 438.
Active group: n = 1483. T1: n = 494; T2: n = 495; T3: n = 494.
