From: The early minutes of in-hospital cardiac arrest: Shock or CPR? A population based prospective study
Estimated probability of survival among patients with VF/VT, according to time to first defibrillation (≤ 10 minutes), and to whether BLS CPR was provided or not. Logistic regression coefficients with 95% confidence intervals in parentheses: Model r-square = 0.26, Intercept = 0.84 (-0.17 to 2.06), CPR = -2.35 (-4.25 to -0.74), Log (time [min]) = -1.35 (-2.32 to -0.61), Interaction term = 1.74 (0.61 to 3.05).
