Differences in systemic complement levels and complement GRS in AMD patients and control individuals. (A) FH, (B) C3bBbP levels in plasma and (C) the complement GRS are shown for non-carriers and CFH rare variant carriers stratified by phenotype (no AMD, early/intermediate AMD and advanced AMD). (A–C) Mean and SD are shown by error bars, and (A, B) mean ± 2 SD is indicated by dotted lines. (C) Dotted lines indicate the tertiles of the complement GRS based on a large AMD case–control cohort (de Breuk et al., submitted for publication). Carriers and non-carriers within each AMD stage were compared with one-way ANOVA and Sidak’s multiple comparison test, and significant P-values are indicated with *<0.05, **<0.01, ***<0.001 and ****<0.0001.
