Items analysis of the Frailty Index (FI-35): Insight in the contribution of each item to the level of frailty

<h4>Background</h4> The FI-35 is a valid multidimensional Chinese frailty assessment instrument. Like other scales, functional measures rely on the information the total score provides. Our research aimed to analyze the contribution of each item. <h4>Methods</h4> Descriptive...
