Figure 1.
Forest plot of the associations between having pre-OHCA diagnosed heart disease and survival to hospital admission and survival to hospital discharge. Model 1 adjusted for age and sex. Model 2 adjusted for model 1 plus resuscitation parameters (use of automated external defibrillator, presence of bystander or ambulance witness, provision of bystander CPR, OHCA location and time to defibrillator connection) and model 3 for model 2 plus initial rhythm. Model 4 adjusted for model 3 plus significant cardiovascular risk profile (obesity, hypertension, hypercholesterolemia, stroke, type 2 diabetes) and model 5 additionally adjusted for significant non-cardiac comorbidities (depression, COPD, cancer and renal dysfunction). COPD, chronic obstructive pulmonary disease; CPR, cardiopulmonary resuscitation; OHCA, out-of-hospital cardiac arrest.
