Not all statistical analysis has to be preregistered. If a data has a trend that suggest vaccination might reduce autism I'm sure the researchers would run a test for it.

If the study is underpowered to find a effect in that direction it's also like to be underpowered to find a effect in the other direction.

Can someone with more statistical expertise run a test to see whether the studies are underpowered to pick up effects in either direction?
