Willingness to donate biosamples to a national biobank in Israel: a population-based cross-sectional survey.
Article in Israel journal of health policy research, 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
backgroundIsrael is advancing large genetic and longitudinal studies in personalized medicine through national digital health initiatives. MIDGAM, the Israeli national biobank established in 2014, provides the core biosample and data infrastructure enabling this research. We investigated the willingness to donate samples and linked clinical data for research purposes, and examined preferences regarding the receipt of research-derived information, including incidental findings.
methodsA structured, self-administered questionnaire was distributed electronically to a representative sample of the Israeli population. Participants were asked about their willingness to donate biosamples and linked data, and their opinions regarding receiving results including incidental findings. The data were analyzed by sociodemographic and health characteristics.
resultsThe survey included 1,607 respondents. 52% were willing to donate biosamples, and 40% were also willing to link them with their medical records and to receive incidental results (84.6% of those willing to donate). Individuals most willing to donate and receive research findings, were non-Ultra-Orthodox Jewish, secular, male, aged 30 to 49 years with post-secondary/academic education and above-average income. Additionally, respondents characterized by better general health, being physically active, and absence of chronic or severe illness were more willing to donate biosamples. The main barriers to biosample donation were concerns about data leakage, privacy violations and lack of understanding of the donation purpose.
conclusionIsrael's biosample donation landscape mirrors global patterns, with notable sectorial and demographic disparities. Higher socioeconomic status and health engagement increase willingness to donate, while privacy concerns and the perceived burden of continued involvement reduce participation.
