Note. FY = fiscal year. All variables presented were significant in χ2 analysis at the P < .001 level, with the exception of the Charlson score, for which t test was more appropriate because of low numbers in some cells. Differences by suicide-related behavior category in mean Charlson score were also significant at the P < .001 level.
