Fig. 1.
Genome-wide plots for the meta-analysis results of whole-brain skeletal FA and processing speed. a q–q plots of meta-analysis results of FA (λ = 1.02, SE = 5.42 × 10−6), and processing speed (λ = 1.01, SE = 3.56 × 10−6) with the diagonal line representing the expectation under the null hypothesis of no association. b Distribution of log-transformed P values (Y-axis) from the meta-analysis of FA and processing speed for 6.12 million SNPs tested plotted against the chromosomal positions (X-axis). The red line represents the genome-wide significant threshold of 5 × 10−8 and the blue line represents the threshold for suggestive evidence of 10−6
