Conceptualizing psychological capacity.
Article in The journal of nutrition, health & aging, 2026. 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
Intrinsic capacity is being increasingly used as an entry point for clinical care and as a research outcome, yet basic work on measurement of its subdomains has lagged. Psychological capacity illustrates the challenge: despite its conceptual breadth, most studies limit measurement to symptoms of depression, capturing only a fraction of the construct. This editorial discusses a consensus-building effort by Hagani et al. in this issue that offers a clearer definition of psychological capacity and a replicable process for sharpening intrinsic capacity's other subdomains. It argues that conceptual clarity must now be followed by measurement tools that move the field beyond depressive symptoms while being psychometrically sound, available in brief and comprehensive forms, and sensitive to change.
