CONSTANCES, the French nationwide population cohort: major accomplishments.
Article in European journal of epidemiology, 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
The CONSTANCES cohort is an epidemiological research infrastructure accessible to the international epidemiologic research community (doi.org/ https://doi.org/10.13143/inserm_constances ). CONSTANCES also provides public health authorities with data regarding prevalence of numerous health conditions and determinants among the French population. CONSTANCES comprises a representative sample of about 220,000 French adults aged 18-69 at enrolment (7.6% participation rate). Follow-up begins at enrolment and is intended to last for the lifetimes of study participants. At inclusion, the selected subjects completed questionnaires and underwent a comprehensive health examination. A biobank was established. The follow-up includes a yearly self-administered questionnaire, and a health examination every four years. Social and health data are collected continually from French national administrative databases. The data collected cover a wide spectrum of somatic and mental health disorders, social and demographic characteristics, socioeconomic status, life events, behaviors, environmental and occupational factors. In order to estimate prevalences that are unbiased by non-participation, weighting methods based on data from national administrative databases were developed. The CONSTANCES research infrastructure is open to legitimate researchers from any country, on any topic for which a sound research project is proposed, and for which certain ethical conditions are met. Up to 2025, over 200 projects have been conducted and more than 250 papers have been published; the numbers are expected to grow as the participants age. Highlighting the broad scope of CONSTANCES data collection, already published papers pertain to many health research fields, such as chronic diseases, aging, women's health, environmental and occupational risks or research methods.
