Management Strategies for Generalised Granuloma Annulare: A Systematic Review of Current and Emerging Therapies.

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
Generalised Granuloma Annulare (GGA) is a chronic inflammatory skin disorder with no standard treatment. Since the last review in 2013, new treatments and varied responses have highlighted the need for an updated synthesis to guide clinical decisions. This systematic review aimed to evaluate the epidemiology, comorbidities and treatment outcomes in patients with GGA, synthesising evidence from published studies to provide insights into both conventional and emerging therapeutic strategies. A systematic literature search was conducted in CENTRAL, Embase and PubMed, following PRISMA guidelines. Studies published in English, French or Spanish up to January 15, 2024, were included. Data extraction focused on patient demographics, comorbidities, treatment regimens and therapeutic outcomes. A total of 689 patients were included. The mean age of patients was 52.8 years, with a female predominance (72.6%). Based on this systematic review, we propose a stepwise approach: first-line treatment includes hydroxychloroquine and phototherapy (PUVA > UVA1 > nb-UVB). Oral corticosteroids along with high-potency topical steroids or calcineurin inhibitors may be used in extensive or rapidly progressive disease or as bridging therapy pending slower-acting agents. Sulfones are second-line, with oral retinoids (e.g., isotretinoin) as alternatives if contraindicated. For refractory cases, off-label anti-TNF-α agents or JAK inhibitors are recommended, with methotrexate or cyclosporine as valid alternatives. This largest systematic review of GGA treatments offers an evidence-based clinical framework. While steroids and phototherapy remain standard, emerging options like JAK inhibitors and biologics show promise for refractory cases. Tailored, multimodal strategies may improve outcomes, though further trials are needed to standardise guidelines.
