WebTherefore, there may be an information deficit in the GWAS data we used, which may underestimate the effect of neonatal jaundice on ASD. There are some limitations of this study. First, because the original screening criteria of p < 5 × 10 −8 were set, which reduced the number of SNPs available for analysis, we relaxed the screening criteria ... WebForest plots of the marginal SNP effects at the 5 × 10 −6 GWAS significance threshold show that the confidence intervals for all meta-analyses included the null value (Fig. 8). In particular, the Egger regression and IVW causal estimates, which were consistently furthest from the null value, had very large variances that drove our null findings.
