Note: Analyses controlled for ethnicity. Caucasians served as the reference group against which African Americans and others were compared. General effect of ethnicity was not significant in the multivariate analyses predicting any falls (Wald=2.56, p=.633), single falls (Wald=1.066, p=.587) and recurrent falls (Wald=2.723; p=.256). Specific comparisons between the reference and other two groups were not significant.
