Model-1: without adjustment for any variable; Model-2: after adjustment for age and body mass index; not normally distributed; Spearman’s correlation coefficient calculated. All values expressed as correlation coefficient ( value); considered statistically significant; TSH: thyroid stimulation hormone; TPO: thyroid peroxidase; T3: tri-iodothyronine; T4: tetraiodothyronine.
