Comparison of anthropometric and hormonal data between girls of group PA+/AT+ and those of groups PA−/AT−, PA−/AT+ and PA+/AT−.

Variable	Group PA+/AT + vs. Group PA−/AT−	Group PA+/AT + vs. Group PA−/AT+	Group PA+/AT + vs. Group PA+/AT−
	P value
BMI	0.012	0.279	0.261
Leptin	0.026*	0.788	0.542
TSH	0.016	0.955	0.043
FT4	0.056	0.529	0.082

Group PA−/AT+, girls with autoimmune thyroiditis (AT) but no premature adrenarche (PA); Group PA+/AT−, girls with PA but no AT; Group PA+/AT+, girls with PA and AT; Group PA−/AT−, girls without PA or AT (controls).

Vs: vs.; BMI: body mass index; TSH: thyroid-stimulating hormone; FT4: free thyroxine.

^*We used linear regression to investigate whether leptin levels differed among the four groups when adjusting for the effect of BMI. Group PA+/AT+ did not differ significantly from any other group, when adjusting for BMI. The only statistically significant difference after adjusting for BMI was observed between Groups PA−/AT+ and PA−/AT− (p = 0.048). All other pairwise comparisons were not statistically significant.
