Univariable and multivariable analyses of prognostic factors for ICU survival according to adequacy of energy delivery.
| Parameter | Univariable | Multivariable | ||
|---|---|---|---|---|
| HR (95%CI) | p-Value | aHR (95%CI) | p= | |
| Mean Energy del. ≥70% vs. <70% of requ.* | 0.395 (0.197–0.794) | 0.009 | 0.372 (0.182–0.760) | 0.007 |
| Age | 1.068 (1.026–1.112) | 0.001 | 1.094 (1.031–1.162) | 0.003 |
| SAPSII at ECMO Start | 1.037 (1.005–1.069) | 0.023 | 1.009 (0.968–1.051) | 0.677 |
| BMI | 1.042 (0.996–1.089) | 0.074 | 1.071 (1.019–1.125) | 0.007 |
* Patients were divided in two groups according to the adequacy of energy supply (mean calorie delivery ≥70% and <70% of calculated requirements over the course of ECMO therapy). Harrel’s C of the overall model: 0.739 (standard error = 0.044). Abbreviations: del., delivery; requ., requirements; vs., versus; Sequential Organ Failure Assessment Score; SAPSII, Simplified Acute Physiology Score II; ECMO, extracorporeal membrane oxygenation; BMI, body mass index; HR, hazard ratio; aHR, adjusted hazard ratio; CI, confidence interval.
