IL37 and bladder transitional cell carcinoma: Analysis through the Kaplan–Meier Plotter tool (www.kmplot.com; accessed on 1 December 2022) [37] revealed that BLCA patients who expressed high levels of IL-37 (n = 275) or SIGIRR (n = 216) have a greater probability for longer OS compared to those with low expression of these genes (n = 129 and 188, log rank p = 1.8 × 10−2 and 1.5 × 10−5 for IL-37 and SIGIRR, respectively) (Figure 1B).
