Erythromelalgia mimicking diabetic foot infection: diagnostic challenges and contraindication of ice application.
Article in Journal of medical case reports, 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
backgroundErythromelalgia (EM) is a neurovascular disorder with an estimated incidence of 0.25-2 cases per 100,000 people, characterized by episodic burning pain, erythema, and increased skin temperature, primarily in the extremities. Its presentation can be mistaken for diabetic foot infection (DFI), leading to diagnostic dilemmas and potentially harmful therapeutic interventions. CASE PRESENTATION: A 62-year-old Han Chinese woman with diabetes presented with recurrent redness, swelling, burning pain, and ulceration on both feet. She was once misdiagnosed as DFI, but was finally confirmed as EM based on characteristic symptoms (heat intolerance, relief with cautious cooling) in the absence of infectious signs (fever, leukocytosis, or purulence). During the treatment, the patient was significantly alleviated. However, she suffered from gangrene and went through amputation due to use of ice packs.
conclusionThis case not only demonstrates the critical importance of differentiating EM from DFI, but also emphasizes the necessity of avoiding ice therapy in its management, providing valuable insights for clinical practice.
