Text: The beta-carotene effect appeared stronger, but not substantially different, in participants who smoked at least 20 cigarettes daily (RR = 1. 25 ; 95 % CI = 1. 07-1. 46) compared with those who smoked five to 19 cigarettes daily (RR = 0. 97 ; 95 % CI = 0. 76-1. 23) and in those with a higher alcohol intake (> or = 11 g of ethanol/day [just under one drink per day] ; RR = 1. 35 ; 95 % CI = 1. 01-1. 81) compared with those with a lower intake (RR = 1. 03 ; 95 % CI = 0. 85-1. 24).
