Model summary: Nagelkerkes R-Quadrat: 0.036
Notes: Coeff: Estimation coefficient; SE Standard Error; *** p < 0.001; ** p < 0.01; * p < 0.05 The value of 0.033 for Nagelkerker’s R-squared shows that the independent variables in the present model explain some of the variability in the occurrence of an intervention-related complication. This is due to overall complication rates being low. In addition, the model is not intended to predict complications but to analyze whether there is a difference between the surgical procedures
