Glycaemic biomarker trends across pre-war and wartime periods in Ukraine, 2021-2024: a repeated cross-sectional study.
Article in EClinicalMedicine, 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
Background: The ongoing war in Ukraine have exposed the population to unprecedented stressors the long-term metabolic consequences of which remain insufficiently characterised. This study evaluated changes in glycaemic control and related biomarkers in the Ukrainian population during ongoing war between 2021 and 2024. Methods: This large-scale, single centre repeated cross-sectional study analysed routine laboratory data across Ukraine from January 2021 to December 2024. We included a convenience sample of adults aged 18-90 years with complete demographic data who underwent on fasting plasma glucose (FPG) (108,346 individuals), of whom 86,077 also had glycated haemoglobin (HbA1c) results. Additional data was available for 2502 insulin and 9000 cortisol measurements. Biomarker trends were assessed annually and quarterly, stratified by sex, age, and geographic region, and categorised as corresponding to normoglycemia, prediabetes, and diabetes. Findings: In 2021, median HbA1c was 5.71% (interquartile range; IQR 5.34-6.34), with 28.7% of individuals in the prediabetic and 22.3% in the diabetic range. By 2024, median HbA1c rose to 5.91%, with prediabetes increasing from 28.7% to 37.7%, and diabetic levels rate growing from 22.3% to 26.4%. As a result, 64% of all individuals tested in 2024 had HbA1c above the normoglycaemic threshold. Women and working-age adults showed the greatest glycaemic deterioration, despite men having higher absolute levels. Interpretation: The Ukrainian population experienced significant metabolic deterioration during the war. Rising HbA1c and the growing prevalence of prediabetes and diabetes, particularly among women and younger adults, indicate escalating cardiometabolic risks. Future prospective longitudinal studies are needed to evaluate the long-term effectiveness of integrated metabolic and psychosocial interventions in conflict-affected populations.
