Unadjusted and adjusted odds ratios for survival to hospital discharge by day of week among 9,667 patients with out-of-hospital cardiac arrest. Unadjusted odds ratios were derived from a simple logistic regression model exploring the relationship between day of week and survival to hospital discharge. Adjusted odds ratios were derived from a multiple logistic regression model adjusting for sex, age, initial rhythm, witness status, bystander CPR, bystander automated external defibrillator use, EMS response time and ROC site.
