Figure 1.

Volcano plot showing results of NWAS analysis regarding associations between 101 nutrients and dementia risks. The x-axis represents hazard ratio for each nutrient per 1-SD increase in consumption. The y-axis represents q values (FDR-adjusted p values) in -log10 scale. Associations between each nutrient and dementia risks were separately estimated with the fully adjusted Cox proportional hazards regression model. The horizontal and vertical dashed lines represent the threshold of q values at 0.05 and hazard ratios at 1, respectively. Scatters in black, blue, and red mean the p values ≥ 0.05, p values < 0.05 and q values ≥ 0.05, and q values < 0.05, respectively. Abbreviation: CI, confidence interval; FDR, false discovery rate; HR, hazard ratio; SD, standard deviation.
