The model incorporates the subject-specific (longitudinal) random effects, expressed as the logarithm of the odd (logit). The probability of outcome events was constructed with π-GST level and was centered to have an average of zero over the range of the data as constructed with the GAM. Log [π-GST (μg/L)] = 2.7 was an independent factor predicting postoperative stage 2 or 3 AKI or in hospital mortality.
