Incidentally, one of the most important rules of science, or any type of systematic, logical investigation, is that you can't cherry-pick. In order to reach a legitimate conclusion, all information must be considered in fact, the effort is to find ways to reject a hypothesis, not to trawl for support.This is especially important when the goal of work is to provide support for families and for children's mental health. Mistakes can cause unnecessary suffering, whether they are mistakes of design or lack of transparency in reporting (cf. the TREND guidelines).
