^†

Stroke work=(MAP-PCWP)*0.0136*(CO/HR)*1000, where MAP=mean arterial pressure in mmHg, PCWP=pulmonary capillary wedge pressure in mmHg, CO=cardiac output, L/min, and HR=heart rate, bpm

^‡

Secondary analysis demonstrated that vasopressor score was also an independent predictor (p<0.001; odds ratio 2.02 per vasopressor used during CS hospitalization)
