Figure 1. Statistical diagram of a parallel mediation model including 4 mediators.
a: The effect of rs72613567 on the mediator (individual histological score)
b: The effect of the mediator (individual histological score) on the fibrosis score.
ab: The indirect effect of the rs72613567 on the fibrosis score through each mediator (individual histological score).
Total ab: The sum of all indirect effects of the rs72613567 on the fibrosis score through all mediators.
c: The direct effect of rs72613567 on the fibrosis score, not operating through mediators.
c’: The total effect of rs72613567.
