Mortality in Patients with Acquired Perforating Dermatosis: Results from the First Multicenter Case-Control Study.
Article in Dermatology practical & conceptual, 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
introductionMortality data in patients with acquired perforating dermatosis (APD) are limited.
objectivesTo assess, for the first time, the risk of all-cause mortality in adult patients with APD and to explore associated systemic comorbidities.
methodsThis retrospective multicenter case-control study included adult patients diagnosed with APD and age-, sex-, and year-matched controls. We evaluated overall survival and the prevalence of seven major comorbidities: systemic malignancy, chronic obstructive pulmonary disease (COPD), severe liver disease, diabetes mellitus, arterial disease, hypertension, and dyslipidemia. Statistical analyses included univariate comparisons (Fisher's exact test and logistic regression), Kaplan-Meier survival estimates with log-rank tests, and multivariate Cox proportional hazards models.
resultsFifty-one patients with APD and 102 controls (1:2 ratio) were finally included in this investigation. Patients with APD had a significantly increased risk of mortality compared to controls ( log-rank test, P<0.001). In the multivariate Cox regression analysis, arterial disease emerged as the sole independent predictor of mortality (adjusted hazard ratio [HR]:7.716; 95% confidence interval [CI]: 2.774-21.464; P<0.001).
conclusionsThis is the first study to identify a potential association between APD and increased allcause mortality, primarily driven by coexisting arterial disease. These findings highlight the importance of comprehensive management in APD patients and emphasize the dermatologist's role in multidisciplinary care aimed at improving long-term outcomes.
