Underdiagnosis of Health: A Key Driver of Overdiagnosis of Disease.
Article in Journal of evaluation in clinical practice, 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
backgroundIn reducing medical overactivity and healthcare waste, there is much focus on reducing overdiagnosis of disease. Surprisingly, there is little attention on the underdiagnosis of health.
objectiveThis article investigates how avoiding underdiagnosis of health can reduce medical overactivity.
methodsConceptual analysis drawing philosophy of medicine and medical ethics is used to address five specific research questions: 1) What is health? 2) What is underdiagnosis? 3) What is underdiagnosis of health? 4) What is the relationship between underdiagnosis of health and overdiagnosis (of disease)? 5) What are the implications of the answers to questions 1-4?
resultsUnderdiagnosis of health is contingent on the concept of health, e.g. health as wellbeing, capability, homeostasis, well-functioning, sense of coherence, resilience, and ability to realize vital goals. Underdiagnosis is reconceptualized as an epistemic omission that applies as much to health as to disease. On this basis, four types of underdiagnosis of health are identified, three of which are inherently related to overdiagnosis of disease. Unlike overdiagnosis, which is primarily detectable at the population level, underdiagnosis of health can often be identified at the level of the individual clinical encounter. Given the asymmetry of aversion-where omissions are often judged more harshly than commissions-there may be a stronger moral appeal to avoid underdiagnosis of health than to avoid overdiagnosis of disease. However, there are conceptual and practical challenges associated with underdiagnosis of health.
conclusionWhile acknowledging the many challenges with the concept, focusing on underdiagnosis of health may be a fruitful strategy to mitigate medical overactivity including overdiagnosis of disease.
