Weight loss for ephedra + caffeine treated subjects

Variable	`Red' cluster (N = 26)	`Green' cluster (N = 26)	P value
Gender (female/male)	26/0	20/6	N/A
%Weight at baseline	100	100	N/A
%Weight at 1 week	98.88 ± 1.10	98.35 ± 1.32	0.22
%Weight at 2 week	98.30 ± 1.57	97.76 ± 1.55	0.22
%Weight at 3 week	97.62 ± 1.58	97.33 ± 1.59	0.27
%Weight at 4 week	97.48 ± 1.93	96.45 ± 2.19	0.06
%Weight at 8 week	96.87 ± 2.35	95.59 ± 2.75	0.03

A total of 52 subjects were treated with ephedra and caffeine (E+C) for 8 weeks. The weight losses are reported as % weight from baseline. %Weight is body weight/baseline. All the P values were adjusted by using Tukey-Kramer method.
