There are 3 laws of epidemiology
1. There must be something in the data.
2. If there isn't something our analysis must be wrong so change the predictors and definitions and anything else.
3. If you keep at it long enough, you will find something. People who don't find anything aren't trying hard enough.

A place I briefly worked, the senior statistician had been through some data and grouped the predictors in many possible ways. For example compare groups A+B+C to D+E. She then told the clinician that if he could justify one of the significant ones, then he had a paper. I left very quickly.
