Insensitivity analysis—dietary inflammatory index was converted from a continuous variable to a categorical variable (tertiles).
a
β: effect sizes; OR: odds ratio.
b
95% CI: 95% confidence interval.
c
Model 1: no covariates were adjusted.
d
Model 2: adjusted for gender, age, and race.
e
Model 3: adjusted for gender, age, race, education level, serum glucose, serum calcium, serum phosphorus, serum iron, serum C-reactive protein serum, serum 25(OH)D, systolic blood pressure, diastolic blood pressure, body mass index, hypertension, diabetes, chronic kidney disease, protein intake, calcium intake, and phosphorus intake.
