  • a Poisson regression was used to compare the rates for the 5 main groups (labeled 1–5 in the first column). There were significant differences between the 5 groups (P < .001 overall). Group 3 was significantly higher than group 1 (P < .001), whereas groups 2, 4, and 5 were not significantly different from 1 (min P = .49).
