Note: Only first-allowed, lost-time claims have been considered. Confidence intervals were not calculable when "at-risk" estimates were less than 500 full-time equivalents because approximate coefficients of variation for estimates of annual averages for Ontario, 1997 were not available.
NEC = Not Elsewhere Classified.

aRate per 100,000 full-time equivalents (1 full-time equivalent = 50 wks/year * 40 hours/week = 2,000 hours) with 95% CI.
bOccupational categories are presented in order of prevention index rank. Since the prevention index is the mean of the frequency of claims rank and rate of claims rank, rates will not necessarily appear in descending order.
