Figure 1

Quantile-quantile (Q-Q) plots of observed versus expected −log (P) test statistics for: (a) trio samples; (b) case-control samples; and (c) combined trio-case-control samples. The 95% confidence interval of expected values is indicated in grey. Corresponding genomic control lambda values are indicated within each plot.
