Table 2. Counts, Crude Rates, and Adjusted Hazard Ratios for All-Cause Mortality and Suicide Among Women by Handgun Ownership Among Cohabitants.

Variable	Women residing with handgun ownersa		Women residing with adults who did not own handgunsb		Adjusted hazard ratio (95% CI)d
	Deathsa	Crude rate	Deathsc	Crude rate
All cause	4585	418.47	290 374	563.68	1.04 (1.01-1.07)
Suicide	64	5.84	2133	4.14	1.43 (1.11-1.84)
Suicide by firearm	31	2.83	306	0.59	4.32 (2.89-6.46)
Suicide by other method	33	3.01	1827	3.55	0.90 (0.63-1.27)

^a Rate denominators for study participants living with handgun owners consist of the exposure time women who did not own handguns contributed while in such a residential arrangement.

^b Rate denominators for study participants living with only nonowners consist of the nonexposure time women who did not own guns contributed while in such a residential arrangement.

^c Death counts for study participants residing with handgun owners indicate deaths that occurred among women who did not own handguns during a period in which they were residing with 1 or more handgun owners. Death counts for study participants residing with only nonowners indicate deaths among women who did not own handguns during periods in which they resided with only nonowners.

^d Adjusted hazard ratios were estimated with the use of Cox proportional hazards models in which baseline hazards were stratified according to census tract. The models were controlled for age at the beginning of the study period, household size (based on adults on the California voter file), race and ethnicity, and binary indicators of individual and household ownership of rifles or shotguns.
