Upadacitinib Versus Acitretin for the Resolution of Pustules in Palmoplantar Pustulosis During Acute Phase: A Single-Center, Open-Label Prospective Cohort Study.
Trial report in American journal of clinical dermatology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
backgroundPalmoplantar pustulosis (PPP) is a chronic inflammatory skin disease characterized by recurrent pustules on the palms and soles. Current treatments, including topical medications, phototherapy, and systemic therapies, often show limited efficacy. Upadacitinib (UPA), a selective JAK1 inhibitor, has shown potential in treating neutrophilic dermatoses by modulating cytokine activity.
objectiveTo evaluate the efficacy and safety of UPA compared with acitretin (ACI) in the acute phase of PPP through a prospective cohort study.
methodsThis study was conducted at the Shanghai Skin Disease Hospital from August 2024 to January 2025. A total of 79 patients with acute PPP were enrolled and randomly assigned to receive UPA (15 mg daily) or ACI (20 mg daily) for 4 weeks. Efficacy was assessed using pustule counts, Palmoplantar Pustulosis Area and Severity Index (PPPASI), and Dermatology Life Quality Index (DLQI). Safety was evaluated by recording adverse events (AEs).
resultsAt week 2, the rate of complete pustule clearance was significantly higher in the UPA group (41.9%) than in the ACI group (10.5%, P = 0.003). By week 4, all patients in the UPA group achieved a pustule count < 30, compared with 63.2% in the ACI group. The UPA group also showed greater reductions in PPPASI and higher response rates for PPPASI 50/75/90. Quality of life improvements, as measured by DLQI, were more pronounced in the UPA group. In terms of safety, UPA had a favorable profile with lower overall AE incidence compared with ACI.
conclusionsUPA demonstrated superior efficacy over ACI in rapidly clearing pustules and improving skin lesions and quality of life in acute PPP episodes. The findings suggest that JAK1 inhibition may be a promising therapeutic approach for PPP, warranting further investigation in larger trials. CLINICAL
