#Statistics thought of the day: Developing predictions from observational data such as#ehr informs one about PREVAILING outcomes of PREVAILING treatment strategies and has almost nothing to do with what happens if a DIFFERENT treatment were given to a patient.#causalinferenceHvala.

#Statistics & treatment comparison thought of the day: The fundamental therapeutic question (which motivates ANCOVA) is: Do 2 patients starting at the same point except for treatment assignment end up at the same point?

This trial published in
@NEJM got lucky despite using an outcome variable with tragic statistical properties. But a proper outcome variable could have resulted in FAR fewer women being randomized while getting the same power: https://www.nejm.org/doi/full/10.1056/NEJMoa1904351 …#Statistics@EdgeforScholarsHvala.
