Restless legs syndrome or diabetic peripheral neuropathy: diagnostic dilemmas and clinical insights from a case report.
Article in Frontiers in endocrinology, 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
Objective: Diabetic peripheral neuropathy (DPN) comorbid with restless legs syndrome (RLS) is relatively rare and easily causes diagnostic dilemmas due to highly overlapping clinical manifestations. This study aimed to clarify the differential diagnosis and clinical recognition of DPN comorbid with RLS. Research design and methods: A retrospective analysis was conducted on a case of type 2 diabetes with lower extremity discomfort. We reviewed the prevalence of RLS in diabetic neuropathy, its diagnostic workflow, distinguishing features between RLS and DPN, as well as the evolving therapeutic concepts for RLS. Results: The patient presented with 6-month lower extremity discomfort, rest-induced aggravation, movement-related relief, nocturnal exacerbation, and severe sleep disturbance. Nerve conduction study and DPN screening were abnormal. Pregabalin therapy significantly alleviated symptoms. A diagnosis of secondary RLS was confirmed. Conclusions: Secondary RLS is easily confused with DPN. Strict guideline-based assessment and comorbidity management are critical for accurate diagnosis and optimal care.
