Notably, low FT4 levels demonstrated strong positive associations with central adiposity markers in men, significantly increasing the odds of elevated waist circumference (OR = 6.24; 95% CI, 1.57–41.83; p = 0.022) and showing borderline significance for association with high WHtR (OR = 4.74; 95% CI, 1.01–32.39; p = 0.055) in the fully adjusted models.
