Proportionate mortality ratios for suicide for the 398 decedents in Table 1.

The PMRs were generated by LTAS software with 95% CIs and 2-sided P values on the basis of an assumed Poisson distribution; values > 1.0 indicate that the proportion of deaths by suicide is greater than that for the general US population during the study period, with values of P < 0.05 considered significant.
