Table 2 Procedural data. For binary data, the number (n) and proportion (%) of patients are listed with the odds ratio and 95% confidence interval (CI). p-values were calculated using Chi-square or Fischer’s exact tests, as appropriate. Numerical data are listed as median and interquartile range (IQR), and p-values were calculated using a non-parametric two-sided Mann-Whitney U test. The LND p-value corresponds to the Chi-square test comparing no, limited, normal with extended, superextended. We defined LND patterns to conform to the 2023 EAU MIBC guideline definitions (Sect. 7.3.4) [2]. LND: lymph node dissection
