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

introductionImmunoglobulin G4-related disease (IgG4-RD) rarely involves the esophagus, typically causing stenosis that presents significant diagnostic and therapeutic challenges. Due to its rarity and its mimicry of other conditions, obtaining a definitive preoperative diagnosis can be difficult. This report details a case of IgG4-RD-induced esophageal stenosis with initial diagnostic ambiguity, which was successfully managed with mediastinoscopy-assisted esophagectomy (MAE), highlighting this minimally invasive approach in a patient with comorbidities. CASE PRESENTATION: A 70-year-old male with comorbidities, including obstructive pulmonary disorder, presented with progressive dysphagia and epigastric discomfort. Endoscopy revealed a persistent mid-esophageal ulcer and a non-passable circumferential stricture; multiple biopsies were nondiagnostic for malignancy or infection. Given the refractory nature of the stenosis, MAE with gastric conduit reconstruction was performed. The postoperative course was uneventful, and the patient achieved symptom resolution without medication. Histopathological examination of the resected esophagus confirmed IgG4-RD, showing obliterative phlebitis and a dense infiltrate of IgG4-positive plasma cells (80/high-power field; IgG4/IgG ratio 80/85).

conclusionsThis case underscores that IgG4-RD should be considered in the differential diagnosis of refractory esophageal stenosis, even with initially inconclusive biopsies. While serum IgG4 measurement has low sensitivity, it is still recommended. For benign esophageal stenosis of unclear etiology, particularly in patients with significant comorbidities, MAE can be a useful and potentially curative surgical option, offering symptom resolution and the possibility of a drug-free outcome.
