Comparison of time-independent DCAs between the nomogram and independent risk factors. AÂ 30-day DCA of nomogram; BÂ 60-day DCA of nomogram; CÂ 90-day DCA of nomogram. The red solid lines use the truncation value and the green dotted lines use the numeric variables. The DCA curves indicated that the nomogram yielded a higher net benefit compared to other single prognostic factors; the cutoff value grouping model showed better practical application value
