The Prevalence and Burden of Truncal Acne.
Article in Dermatology and therapy, 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
introductionAcne vulgaris is a common inflammatory skin disorder that imposes substantial psychosocial and quality-of-life burden. While most guidelines focus on facial involvement, acne frequently affects the trunk, which further exacerbates symptoms and impairs health-related quality of life (HRQoL). Emerging evidence suggests that combined facial and truncal acne is associated with greater disease severity and psychological distress, yet real-world data remain limited. This study evaluates the prevalence of truncal acne and the HRQoL burden associated with facial acne alone, truncal acne alone, and combined facial/truncal acne in a large secondary-care cohort.
methodsA retrospective analysis was conducted using an ethically approved UK dermatology database (2001-2020) comprising 2038 patients. Acne severity was assessed using the Leeds photometric scale and subsequently categorized as mild, moderate, or severe disease. All patients completed the Dermatology Life Quality Index (DLQI) and Hospital Anxiety and Depression Scale (HADS).
resultsAmong validated cases, 36.3% had facial acne alone, 1.7% truncal acne alone, and 61.9% combined facial/truncal involvement. Patients with combined disease exhibited significantly higher total DLQI scores than those with facial acne alone (p = 0.025). DLQI item analyses demonstrated greater symptom burden (question 1; p = 0.048) and work/study impairment (question 7; p = 0.031) in patients with facial/truncal acne. Total HADS scores were also significantly elevated in this group (p = 0.047), independent of acne severity, indicating increased psychosocial distress.
conclusionsOur prevalence of truncal acne (63.6%, including both truncal-only and combined facial-truncal disease) exceeds previous reports of approximately 50%. The presence of truncal involvement in addition to facial acne was associated with significantly greater health-related quality-of-life impairment compared with facial acne alone. These findings highlight the need for proactive assessment of truncal acne lesions and guideline recommendations addressing truncal acne. Improved recognition and tailored treatment, potentially including agents suitable for facial and truncal acne, may help mitigate the substantial burden associated with acne.
