Hyperhidrosis: Prevalence, Diagnosis, and Stepwise Treatment.
Review in Deutsches Arzteblatt international, 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
backgroundHyperhidrosis, or sweating beyond the physiological amount, can be either focal or generalized and sometimes runs in families. The prevalence of primary idiopathic hyperhidrosis is 2-5%. Secondary hyperhidrosis is associated with specific illnesses and medications. In this article, we discuss the diagnostic evaluation of hyperhidrosis and treatments for it, along with their efficacy and side effects.
methodsThis narrative review is based on publications retrieved from the Medline and Cochrane databases with the search term "hyperhidrosis" and other specific terms relating to treatment. Expert recommendations and guidelines were considered as well.
resultsThe diagnostic evaluation consists of a clinical history, a Minor (starch-iodine) test, gravimetry, and dynamic sudometry. There have been no more than a few high-quality published studies on specific interventions. Depending on the severity and symptom burden, aluminum chloride and anticholinergic drugs are used first, followed by botulinum toxin injections and subcutaneous curettage for axillary hyperhidrosis. These treatments reportedly bring about marked improvement in 60-70 % of patients; their side effects, depending on the particular treatment used, include local reactions such as itch, pain, and cutaneous irritation and anticholinergic effects such as dry mouth, mydriasis, urinary retention, and headache. Further therapeutic options are tap water iontophoresis; radiofrequency, focused ultrasound, and microwave treatment; systemically administered anticholinergic drugs; and thoracic or lumbar sympathectomy for palmar or plantar hyperhidrosis, respectively.
conclusionA variety of methods can be used to relieve hyperhidrosis and improve these patients' quality of life. There have been no more than a few high-quality studies on their efficacy and long-term results.
