Instrumental Variables Methods Reveal Larger Effects of Menopausal Hormone Therapy in the Landmark Women's Health Initiative Clinical Trial.
Article in AEA papers and proceedings. American Economic Association, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Landmark results from the Women's Health Initiative trial showed that random assignment to menopausal hormone therapy (MHT) elevated risks of breast cancer and other adverse events. Recent analyses argue that MHT risks are small. These analyses report intention-to-treat (ITT) effects, ignoring the fact that many women assigned intervention were non-adherent, while many women assigned control initiated treatment. Instrumental variable (IV) methods and adherence data allow us to estimate effects of MHT on compliers who took MHT if and only if assigned. IV estimates show risks and benefits that are substantially larger than the ITT estimates used to inform MHT guidelines.
