Vulnerability in nursing science: a principle-based concept analysis.
Article in BMC nursing, 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
backgroundThe term "vulnerability" is widely used across disciplines and variably defined within nursing, reflecting differing theoretical and methodological assumptions. This ambiguity hinders coherent application in research and practice. A broad understanding of vulnerability in healthcare is susceptibility to risks and/or illnesses, implying the need for special protection or treatment.
methodsTo clarify the concept of vulnerability in nursing, its disciplinary meanings were synthesized and its maturity was evaluated by using a principle-based concept analysis according to Penrod and Hupcey (2005), which was conducted on nursing literature. Databases MEDLINE via PubMed, CINAHL and LIVIVO were systematically searched with defined keywords, and citation searching. Of 1,169 records identified, 49 studies (1983-2024) were included. The evidence was evaluated using the principles of principle-based concept analysis: epistemological adequacy, pragmatic utility, linguistic clarity, and logical coherence.
resultsThree diverging perspectives were identified: (1) vulnerability as a universal human condition; (2) vulnerability as an individual, risk-oriented notion; and (3) vulnerability as a multifactorial state influenced by social determinants of health. Each perspective shapes nursing's approach to individuals in its own way, focusing on different methodologies. The three perspectives have been combined into an integrative concept for nursing. It addresses the individual, community, and healthcare policy levels. The multidimensionality of vulnerability is suitable to support the notion of nursing care for the individual with a view to the social determinants of health. An assessment of the concept across the principles indicates that it is partially mature and requires further theoretical and empirical development.
conclusionsThe analysis provides an integrative concept of vulnerability for nursing science which can serve as a foundation for its disciplinary use and thematic relevance. Further work should develop discriminant definitions vis-à-vis related constructs, advance valid operational measures, and test the concept empirically across settings to support assessment, intervention design, and system-level health policy, health-promotion, and disease prevention strategies.
