Comparison of gene analysis results for different test-statistics.

<p>Gene -log10 p-values from the CD data gene analysis in MAGMA for three different gene test-statistics, comparing analyses using (A) the mean <i>χ</i>² statistic with the top <i>χ</i>² statistic, (B) the mean <i>χ</i>² statistic and the PC regression model and (C) the top <i>χ</i>² statistic and the PC regression model. P-values below 10^–8 are truncated to 10^–8 (grey points) to preserve the visibility of the other points.
