Supplementary Figure 7 : Relationship between the observed P value and power for each of the 170 Crohn’s disease susceptibility variants.

Supplementary Figure 7

Scatterplot of the statistical power to detect a weak general effect (OR = 1.25) plotted against the observed P value in the prognosis analysis for each of the 170 Crohn’s disease susceptibility variants. The line of best fit (dotted line) was calculated by linear regression. Lack of correlation between power and P value is consistent with the null hypothesis that none of the disease susceptibility variants are individually associated with prognosis.
