Evaluation of Capillary Blood Glucose and Chinese Diabetes Risk Score in Screening for Diabetes and Prediabetes Among Elderly Chinese Population: A Cross-Sectional Study.
Article in Clinical interventions in aging, 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: With the prevalence of diabetes on the rise, healthcare systems worldwide are facing a serious burden. This study aims to explore the performance of fingertip capillary blood glucose (CBG), the Chinese Diabetes Risk Score (CDRS) and their combined application in identifying diabetes and prediabetes using glycosylated hemoglobin as a diagnostic criterion. Methods: We conducted a cross-sectional study from April to September 2022, involving 6868 urban and rural residents aged 60 and above in Qiyang City, Hunan Province. We utilized a logistic regression model combined with Receiver Operating Characteristic (ROC) curves to analyze and evaluate the effectiveness of using CBG alone or in conjunction with the CDRS for screening diabetes and prediabetes. Results: The prevalence of diabetes mellitus and prediabetes mellitus was 21.6% and 33.9%, respectively, among the 6868 elderly people. The area under the ROC curve (AUCs) of FCBG (fasting capillary blood glucose), the CDRS≥25 and FCBG+CDRS≥25 for detecting diabetes (prediabetes) were 0.756 (0.571), 0.570 (0.552) and 0.773 (0.590), respectively. The AUCs of RCBG (random capillary blood glucose), the CDRS≥25 and RCBG+CDRS≥25 in identifying diabetes (prediabetes) were 0.769 (0.590), 0.542 (0.526), and 0.775 (0.593), respectively. Conclusion: In large-scale community screening in China, CBG is more effective than CDRS for detecting diabetes in the elderly. The combination of the CDRS and CBG provides a practical and efficient strategy that could improve community-based screening efficiency for diabetes in the elderly. However, the limited accuracy of CBG and CDRS for prediabetes highlights the need for more specific methods in screening this condition.
