Fig. 4.

A graphical representation of the simplest model proposed in the paper, exploiting 2 features, when used with the high-sensitivity (left panel), optimal (central panel) and high-specificity (right panel) cut-offs proposed in the paper. This can be used to easily calculate the outcome of the model for an individual, given their thigh circumference and maximum calf circumference, expressed in cm. Green regions indicate patients classified as not having sarcopenia, while red regions indicate individuals classified as sarcopenic.
