Model performance in the development and validation sample, with protein intake ≤1.0 g/kg adjusted BW/d as the reference standard, at three different cut-off probabilities.

Model performance in the development and validation sample, with protein intake ≤1.0 g/kg adjusted BW/d as the reference standard, at three different cut-off probabilities.以蛋白质摄入量≤1.0克/（千克校正体重（BW, body weight）·日）作为参考标准，在三种不同截断概率阈值（cut-off probabilities）下，开发集与验证集样本中的模型性能。
