The reason is simple: Everyone knows the game is rigged.
This is the era of Clinical Data Theatre, a high-stakes performance where the script is written by whoever is funding the study.
1. The Gerrymandered Endpoint
The dirty secret of orthopedic research is that "success" is a flexible term. If you are a manufacturer trying to prove your new hip stem is superior, you don't pick an endpoint that’s hard to hit—you gerrymander the criteria.
Need to show "superiority" over a cheaper competitor? Don't look at 10-year survivorship (where everyone is the same). Instead, choose a specific, high-sensitivity Patient Reported Outcome Measure (PROM) at the 6-week mark. If you narrow the window and squint at...
