New insights from bidirectional Mendelian randomization: causal relationships between telomere length and mitochondrial DNA copy number in aging biomarkers
Figure 2. Scatter plot (left) and funnel plot (right) for bidirectional Mendelian randomization (MR) analyses. The results labeled (A, B) correspond to the outcomes of the forward MR analysis, while (C, D) represent the findings from the reverse MR analysis. Each point represents an included SNP in the MR analysis, and the color of the lines corresponds to the methods described in the legend.
