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: Foreign body granuloma (FBG) formation is linked to chronic persistent cutaneous inflammation, representing a severe delayed complication characterized histologically by infiltration of multinucleated giant cells and aggregation of lymphocytes. In filler-induced FBG following cosmetic injections, implanted materials represent a key driver of sustained inflammatory responses. Achieving complete resolution remains challenging, with current therapeutic outcomes for FBG being suboptimal. Emerging evidence suggests that Janus kinase (JAK) inhibitors may constitute a promising therapeutic strategy for refractory granulomatous conditions. Objective: This case report describes the successful management of FBG using JAK inhibitors and synthesizes existing literature to evaluate the efficacy, safety, and potential mechanisms of abrocitinib in treating filler-induced cutaneous FBG. Methods: We present a case of post-filler FBG that presents with multiple smooth-surfaced, hemispherical lesions (3-5 mm in diameter) distributed across the entire facial region. The patient was treated with oral abrocitinib (100 mg daily) and prednisone (30 mg daily, tapered over 9 weeks). Clinical outcomes were assessed weekly for 13 weeks through serial clinical photography, dermoscopy, reflectance confocal microscopy, and multispectral imaging. Adverse events, including rash exacerbation, vomiting, dizziness, and fever, were systematically monitored. A comprehensive literature review was conducted to elucidate JAK inhibitors' therapeutic rationale in filler-associated FBG. Results: The patient achieved complete granuloma resolution within 13 weeks following failed corticosteroid monotherapy. No treatment-related adverse effects were observed during the one-month follow-up period, supporting the favorable safety profile of this therapeutic approach. Conclusion: This report provides preliminary evidence for JAK inhibitors' efficacy in managing refractory filler-induced FBG. Large-scale controlled trials are warranted to validate long-term safety and therapeutic benefits.
