The male and female models were statistically significant: X2 (25)=9818.053, p<0.001 and X2 (24)=4053.338, p<0.001. The models estimated R2 as 21.2%–22.3% (Nagelkerke R2) and the variance correctly classified 71.7%–72.6% of the cases.
* Factors included in table were included during backwards stepwise regression and met the inclusion threshold of p<0.05
CABG, coronary artery bypass graft; CR, cardiac rehabilitation; IMD, Index of Multiple Deprivation; PCI, percutaneous coronary intervention.
