Differential effects of dietary supplements on metabolomic profile of smokers versus non-smokers

Table 1 Basic demographics at baseline of study subjects who completed the study

	Overall	Non-smokers	Smokers
Characteristic	(N = 28)	(N = 17)	(N = 11)	P
Mean age, in years (SD)	56.0 (5.6)	55.7 (6.3)	56.3 (5.0)	0.82
Mean BMI, in kg/m² (SD)	24.7 (3.3)	24.0 (2.6)	25.5 (3.3)	0.24
Percentage postmenopausal at baseline	67.9	52.9	90.9	0.45
Percentage using hormone therapy at baseline and during study	14.3	23.5	0.0	0.19
Percentage of subjects with caffeine intake	96.4	94.1	100	0.09

The basic demographics at baseline of study subjects who completed the study were equivalent between smokers and non-smokers. P-values were calculated using t-test or Fisher's exact test (two-tailed). BMI, body mass index; SD, standard deviation.
