Table 2.
Single test performances in detecting recurrences and high risk recurrences in patients undergoing surveillance of non-muscle-invasive bladder cancer (NMIBC). Values are given in %. Pos: positive, PPV: positive predictive value, NPV: negative predictive value, FISH: fluorescence in situ hybridization, and NMP22: nuclear matrix protein 22.
