Validity of the predictive performance of the nomogram in estimating the risk of high Ki67 expression presence in the training cohort (a, n = 148), internal validation cohort (b, n = 41) and external cohort (c, n = 148). The distribution of the predicted probabilities value of high Ki67 expression presence is shown at the bottom of the graphs, separating those with high Ki67 expression (+) and low Ki67 expression (−). The triangles indicate the observed frequencies of high Ki67 expression presence by the deciles of the predicted probability
