The same factor could also be responsible for the inadequate discrimination for hospital mortality&#46; At one year&#44; calibration performance was good for both the overall cohort and the subgroups classified according to their initial risk category or final management option &#40;<a class="elsevierStyleCrossRef" href="#fig0005">Figure 1</a> and <a class="elsevierStyleCrossRef" href="#tbl0035">Table 3</a>&#41;&#46; On the other hand&#44; although the discrimination performance was good when applied to the overall cohort&#44; different results were observed for the subgroups&#59; it was only accurate for low-risk patients&#44; whereas a tendency to underestimate mortality risk among intermediate- to high-risk patients was observed at one year&#46; This underestimation by GRACE 2&#46;0 might be partly related to differences in the underlying reasons for categorizing patients as high risk &#40;e&#46;g&#46; a 90-year-old patient with left ventricular ejection fraction of 15&#37; vs&#46; a young patient in cardiac arrest&#41;&#46; It is also clear that not all variables that might have an impact on prognosis are necessarily included in GRACE 2&#46;0&#44;

it should be emphasized that risk prediction tools can support but not replace sound clinical judgment&#46; There are other potential explanations for the different observations&#44; especially for the subgroups&#46; The reason for inadequate discrimination performance at one year in patients who underwent CABG might be the low number of deaths observed &#40;only 4&#47;54&#41;&#46; In other patients&#44; the good discrimination performance obtained may be related to the appropriateness of proceeding with PCI &#40;e&#46;g&#46;

in the present study&#44; the outputs were given in terms of probability of dying as a &#8216;percentage&#8217; instead of a &#8216;score&#8217;&#44; and the model was designated the &#8216;GRACE 2&#46;0 risk predictor&#8217;

These differences make direct comparison difficult&#44; highlight the importance of conducting validation studies in different patient populations&#44; and may be a potential explanation for the discrepancy observed between the results of this validation study and the GRACE 2&#46;0 study&#46; It should be emphasized that the different results obtained from the present study do not imply that GRACE 2&#46;0 is an inaccurate risk predictor&#59; they only mean that the risk predictor was applied in a different patient population&#46;</p><p id="par0075" class="elsevierStylePara elsevierViewall">Several studies have been conducted regarding validation of the previous risk score &#40;GRACE 1&#46;0&#41;

However&#44; the justification for the higher rate of CAG among low-risk patients even than among intermediate-risk patients was not apparent&#46; One reason for this discrepancy may be the phenomenon known as the &#8216;treatment-risk paradox&#8217;
