Univariate Cox regression analysis showed that the expression of 9 pyroptosis-related differential lncRNAs, namely, MCCC1-AS1, AL008718.3, LINC02604, AL121652.1, AL161729.4, KLF7-IT1, AC007128.1, AC124312.3, and AC007128.2, was tightly associated with overall survival in bladder cancer patients. Here, KLF7 is linked to urinary bladder cancer.
