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 and Aim: Dyspepsia is a common issue worldwide, primarily caused by gastroduodenal disorders. Esophagogastroduodenoscopy (EGD) is the standard investigation of uninvestigated dyspepsia (UID), whereas transabdominal ultrasonography (TUS) is used to evaluate various hepatopancreatobiliary diseases that may mimic dyspeptic symptoms. TUS is widely used among physicians, even though the diagnostic yield remains unclear. This study is aimed at assessing the additional benefit of TUS on EGD in investigating the etiologies of dyspepsia. Methods: This prospective study included patients with UID indicating for EGD at the Division of Gastroenterology, Department of Medicine, Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok, Thailand. All patients underwent both EGD and TUS within 1 month. Lesions identified by both methods were recorded and classified based on their potential to explain dyspepsia. Clinical data and reasons for EGD were also collected. Results: Three hundred and seventy patients with a mean age of 59 were included in the analysis. Dyspepsia-relevant endoscopic findings were present in 24.1% with common diagnoses including erosive gastritis/duodenitis, peptic ulcer, and erosive esophagitis. Conclusion: EGD provides some diagnostic information for dyspeptic patients, with additional TUS offering limited benefit. TUS findings rarely contributed to the diagnosis or necessitated further intervention, indicating that it does not enhance the diagnostic yield of EGD in this study.
