Against the "extend healthspan but not lifespan" cliché.
Article in GeroScience, 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
What is the ultimate goal of biogerontology (the study of the biology of aging)? A fashionable answer these days, often encountered, is that it is to extend healthspan not lifespan. Here we argue that this is a misguided cliché. Experimental research with animal models has demonstrated the possibility of intervening in and retarding the aging process, and extending lifespan. This, to varying degrees, increases both healthspan and gerospan, the later-life phase in diminished health. Considering possible equivalent interventions in human aging it would of course be desirable to maximize the former and minimize the latter. However, should a given intervention extend gerospan, given that it would postpone death (i.e., save lives) it would, in many circumstances, be unethical to withhold it. Life in moderately diminished health is generally preferable to death, and this is reflected in the recognized value of many life-saving medical interventions that do not restore full health. Thus, "extending healthspan but not lifespan" is not a coherent objective for research on aging.
