The Cochran-Mantel-Haenszel test was used to evaluate odds ratios and confidence intervals in all cases and controls, subgroup of cases, and control individuals without diabetes, respectively. Subgroup analysis was done based on age at diagnosis, whether muscle invasive UBC, and gender and grouped on TNM stage and tumor grade.
