The primary outcome was number per hour as an offset/exposure term. Subgroups included sex, race, ethnicity, military service, blood alcohol category marijuana positive on autopsy, current depressed mood or partner conflict, prior suicidal ideation attempts. Formal interaction tests identified significant subgroup variations age, ethnicity where appropriate. Groups interactions subsequently examined using robust Poisson regression models to measure incident ratios (IRRs). Results There age (p < 0.001), = 0.014), level autopsy conflict 0.001). a sharp peak in around 4AM individuals aged 15 24 (aIRR: 3.11 [2.39, 4.05]) 25-34 (aIRR 2.15 [1.63, 2.86]), 6AM 65 74 1.78 [1.40, 2.25]) 75+ 2.25 [1.69, 3.00]). Hispanic had elevated between 10PM 3AM maximal 232% increase 2am 2.32 [1.67, 3.23]). Current increased 8PM to11PM 1AM 11PM 1.53 [1.24, 1.89]). Individuals BAL 0.08 mg/dL showed sustained 4AM; greater 2.33 [1.88, 2.89] 1AM) than those 1.68 2.01] 12AM). Conclusion Nighttime varied significantly conflict.
