Key result
The authors argue that the Hosmer-Lemeshow test is insufficient for validating EuroSCORE II calibration and recommend using the risk-adjusted mortality ratio (O/E ratio 1.058 in validation set).

This letter argues for a uniform statistical approach to determine the significance of the risk-adjusted mortality ratio when calibrating the EuroSCORE II model, rather than relying on the Hosmer-Lemeshow test.
Effect estimate: O/E ratio 1.058
Absolute Event Rate: 4.18% vs 3.95%
This letter argues for a uniform statistical approach to determine the significance of the risk-adjusted mortality ratio when calibrating the EuroSCORE II model, rather than relying on the Hosmer-Lemeshow test.
Nežić et al. (2012) conducted a letter in Cardiac surgery (n=5,553). EuroSCORE II risk stratification model was evaluated on Mortality (observed vs expected) (O/E ratio 1.058). The authors argue that the Hosmer-Lemeshow test is insufficient for validating EuroSCORE II calibration and recommend using the risk-adjusted mortality ratio (O/E ratio 1.058 in validation set).
