One problem with your wrench is that it is statistically not significant. 1:300.
Though I think that your information can be very valid in a research. One problem with statistical research is that if important questions are missing from the survey, the whole effect of the statistics can become invalid without the researcher knowing it.
That makes statistical research so difficult and gives rise to the statement of the three types of lies in increasing form: there are lies, there are damned lies and there is statistics.
At that point much research will be flawed because of wrong assumptions and unfortunately insurance companies are relying on this kind of research when medication is investigated.
Of course there will also be very good research, the type that looks further than only the surface, but I do not have the warm feeling that that is common practice.
