(a) Forest plot of studies examining the relationship between previous infectious mononucleosis and MS. (b) Funnel plot demonstrating no clear evidence of publication bias in these studies. (c) Forest plot demonstrating ORMS for HLA+IM+ persons. (d) Forest plot demonstrating ORMS for HLA–IM+ persons. (e) Forest plot demonstrating ORMS for HLA+IM– persons. (f) Bar chart demonstrating lack of evidence of interaction between HLA-DRB1*1501 genotype and prior IM on an additive, but not multiplicative scale. The dotted line represents the null (OR = 1). (g)–(j) Forest plots demonstrating estimates of interaction – AP, RERI, synergy index, and multiplicative interaction respectively – for studies with individual-level data available. The reference group (with OR = 1) is HLA–IM– individuals for all panels. MIT: multiplicative interaction term.
