*Coefficients represent the estimated number of additional (or fewer) months of case duration associated with the characteristic, relative to the reference group and adjusting for all other covariates. Imputation of missing data permitted all inquest cases in the sample (n=5096) to be included in the multivariable analysis.

†No reference category because external cause categories were not mutually exclusive.
