Results were from the negative binomial regression model, with days between release and death as the dependent variable. Covariates included time spent in jail during the last incarceration, sex, age at death, race/ethnicity, and the number of times incarcerated. Among all covariates, time spent in jail during the last incarceration and number of times incarcerated were significantly associated with the dependent variable.
Predicted mean was computed holding the other covariates at their mean.
Two-sided chi-squared test for the difference in mean days between release and death compared with the reference.
