Table 4. Adjusted Estimates of the Association of BMI with Survival Outcomes in Patients with VF or VT Arrests^*.

[BMI, body mass index; ROSC, return of spontaneous circulation; VF, ventricular fibrillation; VT, ventricular tachycardia]

^*Models included demographic characteristics, initial cardiac arrest rhythm (VF vs. VT or PEA vs. asystole), cardiac arrest location, and time of cardiac arrest, regardless of significance level. In addition, other variables with a univariate association (p<0.10) with each survival outcome were included in final models. These included pre-arrest characteristics (i.e., clinical comorbidities), arrest characteristics, and interventions in place prior to cardiac arrest, as outlined in Table 1.
