There are ways of testing whether the risk increases for everyone (e.g. 
can one measure something correlated with miscarriages which actually 
increases for everyone in a study) or for an unidentifiable 
subpopulation.  Has anyone actually done this? If what you say is true, 
of course, there would be ethical problems in performing such a study.
