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
Background: Grading system for adrenal phaeochromocytoma and paraganglioma (GAPP) is a scoring system used to predict metastatic potential in carotid body tumor (CBT). This study aimed to determine whether ultrasonic parameters are risk factors for a greater GAPP score in CBT. Methods: A total of 68 patients (74 CBTs) underwent CBT surgery with preoperative evaluation of CBT size and perfusion using ultrasound (US). GAPP score was determined. Results: CBTs in patients with a GAPP score of ≥5 (Group 2, n=31) were significantly larger than those with a GAPP score of <5 (Group 1, n=37) (P<0.05). More intraoperative blood loss (IBL) was observed in Group 2 than in Group 1 (P<0.05). In a subgroup of 10 patients who underwent contrast-enhanced US (CEUS), there were no differences between the patients with a GAPP score of ≥5 (n=3) and those with a GAPP score of <5 (n=7) according to the enhancement pattern and quantitative perfusion parameters (P>0.05). Multivariate logistic regression analysis revealed that the maximum diameter of CBT [D Conclusions: The D
