25-Hydroxy vitamin D tertiles: low tertile T1, middle tertile T2, and high tertile T3. Abnormally distributed continuous variables including TG, ALT, and GGT were log-transformed before analysis; however, nontransformed values were displayed for ease of interpretation. : ANOVA test among three tertiles ( test for categorical data). acompared with T1 group. #Statistics was value.
