title: Effects of high-dose oral vitamin A on diarrheal episodes among children with persistent diarrhea in a northeast Brazilian community.
abstract: The mean +/- SEM duration of diarrheal episodes decreased from 7.1 +/- 2.2 days to 4.3 +/- 0.9 days (P < 0.05) while the incidence of diarrheal episodes remained steady (2.2 +/- 0.3 versus 2.4 +/- 0.5 episodes; P = not significant) between two three-month periods before and after the oral administration of a single large age-adjusted dose of vitamin A among children at historical risk for persistent diarrhea in an impoverished Brazilian community.
