Note. NP = Nothern Plains; SW = Southwest. n = 9492; number of events = 4468.
aMain effects Bs are the parameter estimates for the referent group, and interaction effects represent differential effects across birth cohorts, genders, and tribes. The SE corresponding to each parameter estimate (B) is the standard error of the estimate.
