为了验证预测模型以及与传统ESSEN模型比较，通过估计模型的校准来评估预测的准确性，通过一致性指数（C-index）来衡量区分度，并通过决策曲线分析来估计临床有用性和净收益，此外，我们还计算了另一种判别标准--IDI。这段话翻译英语？

### 回答1：

To evaluate the accuracy of prediction, calibration of the model was assessed by estimating the C-index, a measure of discrimination, and the clinical utility and net benefit were estimated by analyzing the decision curve. In addition, another criterion for discrimination, IDI, was also calculated.

### 回答2：
To validate the predictive model and compare it to the traditional ESSEN model, the accuracy of the predictions is evaluated by estimating the calibration of the model. The discriminatory power is measured using the concordance index (C-index), and the clinical usefulness and net benefits are assessed through decision curve analysis. Additionally, we also calculated another discriminative criterion, the integrated discrimination improvement (IDI).
