This example dataset was included to assess the mediation role of DNA methylation in the effect of exercise on prostate cancer progression in a Seattle-based cohort of patients diagnosed with clinically localized PCa. The entire data set contains two sets of p-values from genome-wide testing of 450K CpG sites. Due to space limit, a subset (10 percent) of the full dataset is included in the package for illustration.
The dataset is a matrix containing two columns of p-values for candidate mediators. Column 1 contains the p-values for testing if an exposure is associated with the mediator (alpha!=0). Column 2 contains the p-value for testing if a mediator is associated with the outcome after adjusted for the exposure (beta!=0).
