AKIN stage 3	0.026	(0.008, 0.101)	< 0.001
Peak CRP (mg/L)	− 1.219E-4	(− 0.007, 0.007)	0.972
NT-proBNP (pg/mL)	− 3.45e-5	(− 7.72e-5, 8.207e-6)	0.113
Initial sodium (mMol/L)	− 0.075	(− 0.224, 0.073)	0.322
Sodium at AKI onset (mMol/L)	0.151	(− 0.028, 0.33)	0.098
Initial potassium (mMol/L)	0.01	(− 0.863, 0.883)	0.982
Potassium at AKI onset (mMol/L)	− 1.015	(− 1.864, − 0.166)	0.019

AKIN stage 3 and potassium at AKI onset were identified as predictive
