Begg’s funnel plots and Egger’s p values for each qualifying group/subgroup constructed for -174 G/C for CAD endpoint are displayed in Fig. 2, Panel B and Fig. 3, Panel B (respectively, for dominant and allelic model), while for circulating IL-6 levels endpoint in Fig. 4, Panel B. Each point in these plots represents the OR or SMD obtained for an included study plotted against its standard error (SE). Here, IL6 is linked to coronary artery disorder.
