Association between gene methylation and tumor progression of bladder cancer in different Chinese sub-populations. The histogram demonstrated the association between (A) methylation index, MI or (B) methylation of individual gene with tumor progression in terms of tumor grade, stage and relapse in bladder cancer samples from Taiwan, Hong Kong (HK) and China. Low grade represented grade 1 cases; high grade represented ≥ grade 2 cases. Low stage represented stage < T2 cases; high stage represented ≥ T2 cases. * and **, P < 0.05 and P < 0.01 respectively.
