The results of the sensitivity analysis for the overall association of GBA variations with dementia risk (Supplementary Figure 9), as well as for the GBA mutations (Supplementary Figure 10), GBA polymorphisms (Supplementary Figure 11), N370S mutation (Supplementary Figure 12), L444P mutation (Supplementary Figure 13), and E326K polymorphism (Supplementary Figure 14), consistently demonstrated that no single study had an undue influence on the respective pooled estimates. The gene discussed is GBA1; the disease is dementia.
