*Hosmer-Lemeshow Goodness-of-fit is based on deciles of risk. p values >0.05 indicate good fit (N,N-diethyl-m-toluamide [DEET], p = 0.67; dress, p = 0.68; dusk/dawn, weekdays, p = 0.97; dusk/dawn, weekends, p = 0.91).
†College: some college, college degree, some graduate school, or graduate degree.
