Table 4 Univariate analyses of all blood gas variables which differed in certain endpoint catego-ries (survival, KRT – kidney replacement therapy, ROKF – recovery of kidney function). All variables but venous pH at AKI onset (endpoint ROKF) entered multivariate analysis
From: Multiple blood gas variables predict AKI survival in an independent manner
Variable | Endpoint | AUC | p-value |
|---|---|---|---|
Venous pH at AKI onset | survival | 0.65 | 0.01 |
Venous pH at AKI onset | ROKF | 0.54 | 0.53 |
Venous pCO2 at AKI onset | KRT | 0.67 | 0.01 |
Venous bicarbonate at AKI onset | survival | 0.65 | 0.01 |
Admission arterial pH | survival | 0.71 | 0.004 |
Arterial pH at AKI onset | survival | 0.67 | 0.003 |
Admission arterial pCO2 | survival | 0.65 | 0.005 |
Arterial pCO2 at AKI onset | survival | 0.69 |  < 0.001 |
