Table 1.
Mean values (±SEM) of clinical/anthropometric/laboratory parameters in a subgroup with TSH < 2.5 mIU/L and in the subgroup with TSH ≥ 2.5 mIU/L, evaluated in the group of 280 inpatients with normal thyroid tests. Comparison between subgroups was performed by Student’s unpaired t-test. Statistical significance was determined at the level of p < 0.05. Statistically significant differences are shaded. The level of statistical significance is given in italics. RBC: red blood cells, Hgb: hemoglobin, WBC: white blood cells, FT4: free thyroxine, FT3: free triiodothyronine, TPOAb: thyroid peroxidase antibodies, TgAb: thyroglobulin antibodies, TSHRAb: TSH receptor antibodies, HDLC: HDL cholesterol, LDLC: LDL cholesterol, TGs: triglycerides, CRP: C-reactive protein, ESR: erythrocyte sedimentation rate, IRI: insulin resistance index.
