Differences in mean T and DHT concentrations at baseline according to smoking status

	Total T (nmol/l)			DHT (nmol/l)
	Mean ± SE	Diff	p value	Mean ± SE	Diff	p value
Non-smoker	13.7 ± 0.14			1.53 ± 0.02
Ex-smoker	12.7 ± 0.17	1.00	<0.001	1.38 ± 0.03	−0.15	<0.001
Current smoker	14.1 ± 0.36	0.45	0.219	1.41 ± 0.06	−0.12	0.031

Estimates represent the mean, standard error (SE) and differences (Diff) in hormone concentrations in ex-smokers and current smokers compared to non-smokers and their associated p values
