TABLE 3.

Unadjusted and adjusted multivariable competing risk model for MAKE: AKI non-recovery vs. AKI recovery groups.

Comparator groups	sHR for AKI non- recovery (95% CI)	p-value
Unadjusted
0–2 days	2.44 (1.99–2.99)	< 0.001
3–7 days	1.73 (1.38–2.17)	< 0.001
> 7 days	1.10 (0.81–1.50)	0.530
Adjusted
0–2 days	2.63 (1.87–3.73)	< 0.001
3–7 days	1.79 (1.28–2.50)	< 0.001
> 7 days	1.26 (0.80–1.98)	0.328

Note: Covariates in multivariable competing risk model: age, sex, race, ascites, race, ascites, alcohol cirrhosis, baseline eGFR, MAP at time of AKI, MELD-Na at time of AKI, SBP infection, peak AKI stage ≥2, ICU transfer during index hospitalisation, and vasopressor use during index hospitalisation. Note: AKI recurrence was not included in the model as patients with non-recovery could not have AKI recurrence as they did not achieve recovery.

Abbreviations: AKI, acute kidney injury; CI, confidence interval; eGFR, estimated glomerular filtration rate; MAP, mean arterial pressure; MELD-Na, Model for End-Stage Liver Disease Sodium; SBP, spontaneous bacterial peritonitis; sHR, sub hazard ratio.
