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
backgroundThe diagnosis of gastric inflammatory fibroid polyps (IFPs) mainly depends on pathological confirmation after endoscopic or surgical treatment. Gastric IFP have typical manifestations under endoscopic ultrasonography (EUS), but atypical EUS features have also been reported. Previous studies have found that atypical features of gastric IFPs observed under EUS have corresponding histological manifestations. At present, there is no study elaborating the EUS manifestations of gastric IFPs at different pathological stages. We hypothesize that gastric IFPs at different pathological stages may have different EUS features.
aimTo describe EUS features of gastric IFPs and compare with their pathological characteristics.
methodsClinical data of 53 inpatients with pathologically diagnosed gastric IFPs after endoscopic treatment were collected. All patients underwent preoperative EUS. We analyzed the EUS characteristics of the lesions and compared with the pathological characteristics and staging of the resected specimens.
resultsMost gastric IFPs showed medium-low echo (67.9%), homogeneous echo (90.6%), and unclear boundaries (83%), and involved the second and third layers of the gastric wall (69.8%) under EUS. The echogenicity level and echo homogeneity were significantly correlated with the pathological stage of gastric IFP. Gastric IFPs in the nodular stage presented hypoechoic and homogeneous echo. Gastric IFPs in the fibrovascular stage mostly showed medium-low echo and homogeneous echo. Gastric IFPs in the sclerotic stage showed different echogenicity levels and echo homogeneity. The accuracy of EUS in diagnosing gastric IFPs was 66.0% (35/53), and the accuracy in determining the origin layer of gastric IFPs was 73.4% (39/53).
conclusionGastric IFPs at different pathological stages have different EUS features. In order to improve the diagnostic rate, it is necessary to combine EUS with EUS-guided fine-needle aspiration or artificial intelligence.
