I read this article and then read the study that it's based on and I noticed something that makes me skeptical:

>We excluded 91 individuals with implausible baseline dates for LMP.

So, out of a study involving 2000 women they excluded 91 based on "implausible" last menstrual period when there is a noted correlation between the vaccine and menstrual irregularities.

My question is: Is this normal for a scientific study? That they exclude data without giving a detailed justification?
