Participants stop treatment, miss visits, or take other medications. A single result has to decide what to do about that, and different decisions give different numbers. The estimand framework, formalised in regulatory guidance, requires the decision to be stated in advance and the result labelled with it.
This replaced older, looser terms such as intention-to-treat and per-protocol with precise definitions.
The treatment-regimen estimand asks what happened to people assigned to each group, whatever they did afterwards — the pragmatic question. The efficacy estimand asks what the treatment does in people who take it as intended — the pharmacological question. Trials in this class report both, and the NEJM paper does.
The efficacy estimand produces the larger weight figure; the treatment-regimen estimand includes those who stopped and is smaller.
A large gap between the two says many people stopped or deviated. A small gap says adherence was high. Reading only the larger figure without noting which estimand it is overstates what a population assigned to treatment would experience.
