- All confidence intervals of AORs for the imputed suicidal ideation with smoking status overlapped with the 95% CI for the AOR observed for the self-reported suicidal ideation with smoke status
- *Never smoker: had not smoked at least 100 cigarettes; former smoker: had smoked at least 100 cigarettes and had successfully quit smoking; current smoker: had smoked at least 100 cigarettes and had not successfully quit
- †Adjusted for sex, age, race/ethnicity, marital status, and education
- AOR, adjusted odds ratio; CI, confidence interval; PCL-C, PTSD Checklist−Civilian Version; PHQ, Patient Health Questionnaire; PTSD, posttraumatic stress disorder
- Self-reported suicidal ideation was indicated if reported “several days” or more to “thoughts that you would be better off dead or hurting yourself in some way”
- PHQ-BIN model: treated suicidal ideation as a dichotomous variable and included the remaining 8 PHQ items in the imputation model
- PHQ-ORD model: treated suicidal ideation as a 4-level variable and included the remaining 8 PHQ items in the imputation model
- ALL-BIN model: treated suicidal ideation as a dichotomous variable and included the 8 PHQ items and previously identified factors from the literature: sex, age, race/ethnicity, marital status, education attainment, 10 individual items from the RAND physical functioning module, 17 individual items and PTSD screener from the PCL-C, smoking status, sleep duration, and 5 alcohol use items from the PHQ [27,28,29,30]
- ALL-ORD model: treated suicidal ideation as a 4-level variable and included the 8 PHQ items and previously identified factors from the literature: sex, age, race/ethnicity, marital status, education attainment, 10 individual items from the RAND physical functioning module, 17 individual items and PTSD screener from the PCL-C, smoking status, sleep duration, and 5 alcohol use items from the PHQ [27,28,29,30]
