Figure 4 showed the funnel plots of meta-analyses evaluating the relationship of the CD24 Ala57Val polymorphism with MS and SLE in recessive model (Fig. 4A for MS and Fig. 4B for SLE). The shape of each funnel plot seemed symmetrical. The results of Begg's test and Egger's test suggested no evidence for publication bias (Table 3). Here, CD24 is linked to systemic lupus erythematosus.
