1 · What the graph read from 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.

2 · The registry

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

backgroundMyasthenia gravis (MG) is a chronic autoimmune disorder affecting the neuromuscular junction, where autoreactive immunoglobulin G (IgG) plays a key role in disease pathogenesis. The novel biologic Efgartigimod is a neonatal Fc receptor (FcRn) antagonist, promotes the lysosomal degradation of IgG, and may offer a targeted approach for managing MG. Despite the growing interest in efgartigimod, there remains a lack of comprehensive evaluation of its efficacy and safety in different MG subtypes.

methodsComprehensive retrieval and screening were conducted on Pubmed, Embase, Web of Science, and Cochrane library to search studies on efgartigimod treatment. The data on response rates and adverse events were extracted, and the pooled effect size (ES) with the 95% confidence interval (CI) was calculated by fixed or random effect models. Sensitivity analysis and subgroup analysis were employed to test the heterogeneity. Funnel plots and trim-and-fill methods were used to test for publication bias.

resultsData from 10 studies involving 305 patients were analyzed. The overall treatment response rate was 78% (95% CI: 67%-87%, I

conclusionOur study demonstrates that efgartigimod is highly effective and well-tolerated in patients with refractory MG. These findings suggest that efgartigimod is a promising drug for the treatment of MG.
