Efficacy and safety of small molecule drugs in the treatment of pityriasis rubra pilaris-A systematic review.
Synthesis in Frontiers in medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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: Pityriasis rubra pilaris is a chronic, scaly, keratotic skin disease, mainly manifested as scaly plaques and keratinized hair follicles. This condition significantly impacts the patient's quality of life and is considered one of the intractable diseases in dermatology. Currently, no satisfactory clinical treatment options are available for this condition, presenting a considerable challenge for dermatologists. We conducted this systematic evaluation to assess the therapeutic potential of existing small molecule drugs for this disease. Objectives: To conduct a systematic review of the existing literature on the use of small molecule drugs for treating pityriasis rubra pilaris and to evaluate their clinical effectiveness and safety. Methods: We conducted a systematic review of all the literature on small molecule drugs for the treatment of Pityriasis rubra pilaris and searched several databases until November 2024, including PubMed, Embase, Web of Science, and the Cochrane Library. Results: A total of 16 patients with pityriasis rubra pilaris from 11 publications were included. The small molecule drugs, including apremilast, upadacitinib, abrocitinib, and tofacitinib, demonstrate good efficacy and safety in the treatment of pityriasis rubra pilaris across all ages, particularly in patients who have failed systemic therapy and have a poor response to biological agents. However, the conclusions are limited by the small sample size and need to be further confirmed through large-scale randomized controlled clinical trials. Conclusion: Small molecule drugs demonstrate favorable clinical efficacy and safety in the treatment of refractory pityriasis rubra pilaris, exhibiting a relatively rapid onset and a high safety profile. However, the findings in the literature may be affected by publication bias.
