Clinical Characteristics and Treatment Patterns of Hyperhidrosis in Northern Hokkaido: A Single-Center Retrospective Descriptive Study.
Article in The Journal of dermatology, 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
Hyperhidrosis is a common condition associated with a substantial negative impact on the quality of life. Several studies have described the clinical characteristics and disease burden of patients with hyperhidrosis in Japan. However, comparable real-world clinical data on hyperhidrosis from Hokkaido remain limited. We therefore evaluated real-world clinical practice patterns at our institution before and after the establishment of a specialized outpatient clinic for hyperhidrosis. In this retrospective study, we analyzed the data of 144 patients who presented with hyperhidrosis between November 2013 and March 2025. Patient characteristics, pathways to care, treatment modalities, and treatment continuation were evaluated using data from electronic medical records. The sex distribution, age at presentation, and subtype distribution of hyperhidrosis in our cohort were largely consistent with those reported in a prior nationwide survey. Primary axillary and/or palmar hyperhidrosis accounted for 87.5% of all cases. After launching a specialized clinic in April 2023, we observed a substantial increase in the number of patients who consulted for hyperhidrosis during visits for other dermatologic conditions; this finding may suggest the presence of previously unrecognized patients. However, changes in hospital access policies may also have influenced consultation patterns. The treatment continuation rates for axillary and palmar hyperhidrosis were both approximately 40%. Among the treatments for axillary hyperhidrosis, sofpironium bromide gel was prescribed most frequently, whereas glycopyrronium tosylate hydrate wipes showed a higher treatment continuation rate. In conclusion, the presence of a specialized outpatient clinic may improve access to care for patients with primary focal hyperhidrosis and facilitate the identification of previously unrecognized patients. However, treatment continuation remained suboptimal, highlighting the importance of improving continuity of care in hyperhidrosis management at our institution.
