Figure 2: Galbraith plot of associations between MTR A2756G polymorphisms and AD risk, produced by first dividing each estimate by its standard error (se) to generate z-statistics (b/se(b)), which is then plotted versus 1/se(b) for each of studies. Inner line represents pooled effect and outer lines represent 95% limits. Each author represents the respective study included in the meta analysis (shown in Table 1) for the indicated association by AA vs. AG+GG (a) and A vs. G (b).
