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

Elevated Immunoglobulin G4 (IgG4) levels have been implicated in various autoimmune and inflammatory diseases, including those affecting the nasopharynx and laryngopharynx. The current systematic review and meta-analysis aimed to determine the prevalence of elevated IgG4 and associated risk factors in patients with nasopharynx and laryngopharynx diseases. This systematic review and meta-analysis were conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A comprehensive search of PubMed, Embase, Web of Science, and Scopus databases was performed from inception until July 2024. Keywords and Medical Subject Headings (MeSH) terms A random-effects model was used to pool prevalence estimates, and heterogeneity was assessed using the Supplementary Information: The online version contains supplementary material available at 10.1007/s12070-024-05189-3.
