Lipid profile in different FT3 and BMI categories.

We stratified the study group according to BMI levels: BMI < 25 kg/m²: normal-weight group; BMI ≥ 25 kg/m²: overweight/obese group. Then, we stratified each group according to serum FT3 levels; and all continuous parameters were presented as mean ± standard deviation, after adjustment for age and gender. For skewness distribution data, median and interquartile range was used. values were calculated from ANOVA (analysis of variance, between categories), after adjustment for age and gender. Significant associations are indicated in bold. was considered statistically significant. , .
