In their study related to predicting survival in peritoneal dialysis, Tangri et al (2008) determine the following results of a logistic regression (where AUROC refers to the area under the receiver operating characteristic curve)
‘The AUROC for the LR model was 0.709 and 0.0208, (P = 0.0164)’

neural networks and logistic regression Nephrology Dialysis Transplantation (2008) 23: 2972–2981 Oxford University Press)
A. What does this reflect in terms of the study and its data?The result is not significant, indicating that technique failure is not correlated with number of days since peritoneal dialysis was initiated.
B. The result is significant and suggests that technique failure necessitates a switch to haemodialysis.
C. The result is not significant but suggests that technique failure is positively correlated with number of days since peritoneal dialysis was initiated.
D. None of the above.
