Weight Gain and Serum TSH Increase within the Reference Range after Hemithyroidectomy Indicate Lowered Thyroid Function

Table 2

Comparison between study groups at baseline.

Variables	Control group; (𝑛=47)	Hemithyroidectomy group; (𝑛=28)	𝑃 value
Males (%)	19.2%	21.4%	0.81*
Age (years)	53 (43–62)	51.5 (43–60)	0.59
Weight (kg)	69.3 (62.2–81.4)	75.0 (63.5–85.0)	0.43
BMI (kg/m^2)	25.0 (22.7–29.0)	26.1 (23.1–28.3)	0.65
Smokers (%)	8.5	14.3	0.43*
TPO-ab positivity (%)	12.8	14.3	0.85*

The Mann-Whitney 𝑈 test was used for continuous variables (median and interquartile range are presented). *Chi-square test for categorical variables. Significant difference was defined as a 𝑃 value < 0.05. BMI: body mass index; TPO-ab: thyroid peroxidase antibody.
