One-year outcome trends in Japanese patients with rosacea: insights from a real-world study.
Article in Skin health and disease, 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
Background: Rosacea is a chronic inflammatory disorder that primarily affects the facial region, significantly impacting quality of life (QOL). Outcomes in patients with rosacea may vary significantly depending on ethnicity, climatic conditions, healthcare system and cultural background. After unifying these factors, outcomes in rosacea should be evaluated over the long term. Objectives: To examine long-term outcomes in Japanese patients with rosacea using data obtained from a single institution. Methods: In this retrospective observational study, data from 63 Japanese patients with rosacea, including 42 patients who were followed up over 1 year, were analysed. Patients were treated with topical agents, with or without oral minocycline, and advised to avoid common triggers such as sun exposure and skin dryness. These data were evaluated using the Dermatology Life Quality Index (DLQI), visual analogue scale (VAS) and Investigator's Global Assessment (IGA) scoring systems. Results: Baseline data for the 63 patients showed that QOL was commonly impaired by uncomfortable sensations, such as itch, as well as by disfigurement. Most patients considered rosacea to have a small-to-moderate impact on their lives. DLQI scores were significantly correlated with VAS scores for itch, burning sensation, flushing and hypersensitivity. IGA scores were significantly correlated with VAS scores for flushing and with DLQI scores. Follow-up data for 42 patients over 1 year showed that VAS scores for itch, burning sensation, flushing and hypersensitivity, as well as DLQI and IGA scores, were significantly decreased over time. Topical therapies did not affect the scores throughout the clinical course. Conclusions: This study was conducted at a single institution in a specific geographical and climatic setting for Japanese patients with rosacea. These findings may inform follow-up care for Japanese patients and contribute to the exploration of ethnic and geographical variations in the presentation and progression of rosacea.
