Figure 2:

Predicted probability* of good neurological function at hospital discharge [defined as a modified Rankin Scale (mRS) ≤ 3 at hospital discharge] in relation to mean partial pressure of arterial carbon dioxide (PaCO₂) during the first six hours after return of spontaneous circulation among patients with a metabolic acidosis (defined as one or more recorded base deficit ≤ −6 during the initial six hours after ROSC). Shaded area, 95% confidence intervals.

*Predicted probabilities calculated using Poisson regression model with robust standard errors adjusting for initial cardiac arrest rhythm, age, airway dead space (corrected minute ventilation for normal PaCO₂), mean arterial blood pressure, and percutaneous coronary intervention (yes/no).
