BMI	-0.03 (−0.05; −0.01)	0.01	0.006*
Age	0.02 (0.01; 0.02)	<0.01	< 0.001**

Symptoms of depression	-0.67 (−1.14; −0.21)	0.24	0.005*
Model 2 - Modified multiple regression
Constant	1.33 (0.22; 2.43)	0.56	0.019*
Female sex	-0.47 (−0.76; −0.18)	0.15	0.002*

Model 1: R² = 0.30. Adjusted R² = 0.28. Delta R² for model 1 incl. HS and symptoms of depression = 0.023. p = 0.012.

Model 2: R²=0.32. Adjusted R²= 0.30. Delta R² for model 2 incl. interaction term HS x BMI = 0.019. p = 0.021.

B-values are presented with 95% confidence interval (95% CI). BMI: body mass index; HS: hidradenitis suppurativa; SE: standard error of b-values.

^*Significant (p < 0.05).

^**Highly significant (p <0.001).

SE B: Standard error of B-value.
