Figure 2.

Network plot including demographics, biomarkers and outcomes of interest. The network plot represents one-to-one Pearson correlations performed with z-score normalized biomarkers and log10 transformed uCTX-II to satisfy assumptions of normality. Positive correlation (>0.1)-red, negative correlation (<−0.1)-green. For the measurements derived from the same biomarkers (e.g. LBP baseline, TIC(LBP)12, TIC(LBP)12), we do not show their correlation since we are mainly interested in correlation among different biomarkers and other measures.
