Figure 3. Assessment of goodness of fit in the 3 risk groups for the derivation cohort (A) and the validation cohort (B).

Figure 3

The observed and predicted rates of postprocedural dialysis for TRITAVIpre risk score in the derivation and validation cohorts showed a Hosmer‐Lemeshow goodness of fit: P=0.31 in the derivation (A) and P=0.25 in the validation group (B). Need for dialysis increased gradually in particular in the highest of 3 risk score groups (from 0.3% to 3.9%). The observed and predicted rates of postprocedural dialysis for TRITAVIpost score in the derivation and validation cohorts showed a Hosmer‐Lemeshow goodness of fit: P=0.58 for the derivation (A) and P=0.84 for the validation group (B). Need for dialysis increased in particular in the highest of the 3 score groups (from 0.1% to 6.2%). The corresponding risk score thresholds for each risk group were ≤2, 3 to 6, and >6 in TRITAVIpre, and ≤6, 7 to 11, and ≥12 in TRITAVIpost. Blue bars indicate observed values and orange bars indicate predicted values. TRITAVI indicates transfusion requirements in transcatheter aortic valve implantation.
