Decision-curve analysis of bladder cancer progression using NMP22, age and gender in 2,222 patients with previous non–muscle-invasive bladder urothelial carcinoma and negative cytology. Age and gender alone were not different from performing a cystoscopy on all strategy. Dashed line: prediction model with NMP22, age and gender. Horizontal line along x axis: assumes all patients will experience disease progression (= all patients need to undergo cystoscopy). Solid grey line: assumes no patient will experience disease progression (= none of the patients needs to undergo cystoscopy).
