Development and internal validation of a rapid bedside score for predicting in-hospital mortality in acute heart failure

Figure 2 Calibration plot. A: The Fast Assessment Score for triage in heart failure (FAST-HF) multivariable model for in-hospital mortality prediction. Calibration analysis showed acceptable agreement between predicted and observed mortality probabilities; B: The FAST-HF bedside score for in-hospital mortality prediction. The bedside FAST-HF score showed acceptable calibration, with observed mortality rates generally.
