From: Evaluation of circulating plasma proteins in breast cancer using Mendelian randomisation

Mendelian randomisation analysis on breast cancer risk in the BCAC study was performed by modelling exposure to genetically higher plasma levels of 730 proteins with at least one cis-pQTL. The Y-axis shows the −log10 p-value of the Wald-score or IVW and the X-axis shows the beta-estimates of the MR result for each protein that was tested.
