Primary and secondary outcomes for a subgroup of individuals with obesity, defined as BMI ≥ 30kg/m2 Odds ratios and p-values are adjusted for age, gender, initial rhythm, witnessed status and time-to-epinephrine.

IO = intraosseous; PIV = peripheral Intravenous; ROR = Rate-of-ROSC; TTR = Time-to-ROSC.
