Correlating consensus modules with age in the ten reference data sets. Each row corresponds to a consensus co-methylation module (defined in Figure 3). More precisely, each row corresponds to the first principal component of each module (referred to as eigengene). The columns correspond to the age variable in each of the ten reference data sets. Each cell reports the correlation coefficient between the eigengene and age (top) and the corresponding P-value (bottom). Cells in the table are color coded using correlation values according to color scale on the right - that is, strong positive correlations are denoted by strong red color, and strong negative correlations by strong green color.
