Preoperative endothelial dysfunction for the prediction of acute kidney injury after cardiac surgery using cardiopulmonary bypass: a pilot study based on a second analysis of the MONS study

Table 3 Stepwise model for predictors of postoperative acute kidney injury

Variables	Odds ratio [95% CI]	p value
CPB time, min	1.024 [1.000, 1.049]	0.052
Peak amplitude, iontophoresis ACh, LSPU	1.045 [1.001, 1.092]	0.045
Body weight, kg	1.057 [1.000, 1.117]	0.049
Age, years	1.091 [1.012, 1.176]	0.024

Variables not retained by the model: hypertension (p = 0.388), sex (p = 0.203), EuroSCORE II (p = 0.747), peripheral artery disease (p = 0.668), chronic obstructive pulmonary disease (p = 0.655), diabetes mellitus (p = 0.366), and type of surgery (coronary arterial bypass grafting (CABG)/valvular surgery) (p = 0.924). Excluded for collinearity: preoperative serum creatinine (with EuroSCORE II) and aortic clamping time (with CPB time)
