The decision curve (A) of the nomogram demonstrated the prediction model had the highest benefit across a wide range of values, together with the clinical impact curve. B Cutoff values of 0.2 and 0.8 were set to define the low-, medium- and high-risk for receiving LLR. C Differences of intra- and postoperative outcomes between corresponding risk levels patients receiving LLR or OLR indicated OLR was more dependable for high-risk patients, while LLR was better in low-risk patients.
