Figure 2

Observed and expected LOD ratio for Average and single visit for top SNPs from meta-analysis, for a subset of individuals that had both visits 1 and 2. Observed LOD score ratio is calculated based on the square of the z-statistics of the Average and the square of (z1+z2)/2 (from z-statistics from visits 1 and 2). Traits on the x axis are sorted by correlation between visits (in parenthesis).
