This tool is used to perform univariate Cox regression analysis, log-rank test and plot KM survival curves for SL and SV gene pairs in multiple cancer types. Based on the SL/SV network in a specific cell type, log-rank prognostic analysis is conducted according to the gene pair alteration profiles of SL/SV gene sets at the bulk level.It was found that the SL gene pair was associated with a good prognosis,and the SV gene pair was associated with a poor prognosis.
