Here I will show results of the univariate analysis of correlation of DNA methylation with clinical traits such as survival, days to tumor recurrence, tumor stage, tumor grade, age, primary therapy outcome and tumor residual disease.
Survival

Method: Cox Proportional Hazards model, P values = Wald's test. This distribution of P values concerns me. If I had no signal the distribution would be rather uniform rather than skewed towards 1. I think it might mean that I have some normalization issues (need to show this plot to Brig)

Why does the distribution look so weird?!!!
