13,265 | I'm trying to figure out if I should be filtering out GWAS hits that have high standard error and I'm not quite sure what to do. It seems like it might not matter, because the standard error is used to calculate the t-statistic, which is then used to calculate the p-value. So in a way it's already built in.

] | I am curious about the relationship between your p-value (or effect sizes) and standard error. I would expect the significant signals to have smaller stand error compared to the non-significant, background signals. If this is the case, there is no need to do filter. | I think the effect size is more of an issue than the standard error.
If the standard error suggests that the effect direction could change sign, then it might be a good idea to filter it out. Otherwise, if the effect size remains large (or at least positive) even after accounting for a large error, then [to me] that w... |
