Cold hypersensitivity in the lower extremities: an underappreciated symptom in patients with varicose veins.
Article in Open heart, 2025. 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
backgroundThis study aimed to investigate the frequently overlooked symptoms of cold hypersensitivity and heavy legs related to varicose veins in a large sample of patients.
methodsData on 8782 adults aged 30-70 years without a history of cancer were sourced from the Taiwan Biobank between 2008 and 2020. Varicose veins, cold hypersensitivity and heavy leg sensations were assessed using questionnaires and analysed using logistic regression models with various covariates. Statistical analyses were performed, with analysis of variance for continuous variables and χ
resultsOur analysis showed significant associations between varicose veins, cold hypersensitivity, and heavy legs (p<0.0001). Logistic regression models showed that moderate and severe cold hypersensitivity increased the risk of varicose veins with ORs of 1.490 (95% CI 1.205 to 1.842) and 1.894 (95% CI 1.546 to 2.320), respectively. Similarly, heavy legs were strongly associated with varicose veins (OR 4.239, 95% CI 3.381 to 5.315), and the interaction between cold hypersensitivity and heavy legs was significant (p=0.0009). Notably, the greatest risk for varicose veins was observed in individuals with heavy legs and severe cold hypersensitivity (OR 7.135, 95% CI 4.980 to 10.221).
conclusionsThe results of this study highlight the clinical significance of considering cold hypersensitivity and heavy legs as vital symptoms for diagnosing varicose veins, particularly in the absence of arterial disorders, which can improve diagnostic accuracy and patient outcomes.
