Six Tx(x) cases were considered as missing data in double/triple vs. single indication analysis
reTURT restaging transurethral resection of bladder tumor; CI confidence interval; NS not significant; OR odds ratio; HG high-grade; LG low-grade; Tx(x) both detrusor muscle and subepithelial connective tissue lacking in the specimen; Tx(a) no intraepithelial invasion within available material, but detrusor muscle lacking in the specimen; Tx (1) intraepithelial invasion within available material and detrusor muscle lacking in the specimen
*Single indication—Tx(a)LG, T1LG, TaHG
**Double indication—Tx(1)LG, Tx(a)HG, T1HG
***Triple indication—Tx(1)HG
