Dermoscopic Evaluation of Mild-to-Moderate Acne Vulgaris: A Correlation Analysis with Clinical Severity Scales.
Article in Clinical, cosmetic and investigational 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
Background: Acne vulgaris is a chronic inflammatory disorder of the pilosebaceous unit. Accurate and objective assessment of inflammatory activity remains a challenge in clinical practice. Dermoscopy, as a noninvasive imaging technique, enables visualization of vascular and color changes associated with inflammation. Methods: In this cross-sectional study, 40 patients with mild-to-moderate acne vulgaris were enrolled, and 80 dermoscopic images were obtained. Background color, vascular morphology, vascular distribution, and perifollicular yellow halo were analyzed and compared between severity grades (mild vs. moderate) and among lesion types (comedonal, papular, pustular). Results: In the mild group, a light-red background predominated (41.7%), whereas red and dark-red backgrounds were more common in the moderate group (both 38.6%), with a significant difference ( Conclusion: Progressive deepening of background color and transformation of vascular morphology on dermoscopy are associated with increasing inflammatory activity in acne vulgaris. Quantitative evaluation of these dermoscopic parameters may contribute to preliminary objective severity grading and therapeutic monitoring. Dermoscopy may represent a potentially valuable, noninvasive imaging modality for assessing inflammatory activity in acne.
