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 Aims: Although upper gastrointestinal (GI) endoscopy is a crucial diagnostic tool for evaluating lesions of the upper GI tract, its findings are not always definitive, necessitating histopathological confirmation. This retrospective study aimed to assess the spectrum of histopathological lesions and their correlation with endoscopic impressions at Methodist Hospital, Wenchi, Ghana. Methods: A retrospective observational study was conducted on patients who underwent upper GI endoscopy with biopsy between August 2024 and September 2025. Out of 513 patients who underwent upper GI endoscopy, 176 were biopsied, but 46 were excluded due to missing histopathology reports, leaving 130 patients for analysis. Endoscopic impressions were compared with histopathological diagnoses across different GI tract sites (esophagus, stomach, and duodenum). Diagnostic accuracy was calculated with sensitivity, specificity, and 95% confidence intervals (CIs). Agreement was assessed using Cohen's Kappa and prevalence-adjusted bias-adjusted Kappa (PABAK). Results: Of the 130 patients, 97.7% of lesions were benign (predominantly chronic gastritis), and 2.3% were malignant. Endoscopy demonstrated a sensitivity of 100% (95% CI: 29.2-100) and specificity of 99.2% (95% CI: 95.8-100) for malignant lesions. Cohen's Kappa was 0.796, indicating substantial agreement, while PABAK was 0.966, reflecting near-perfect concordance after adjusting for prevalence. Conclusion: Upper GI endoscopy showed high diagnostic accuracy and substantial concordance with histopathology for benign lesions such as gastritis. These findings suggest that clinicians in resource-deprived areas where histopathology is not readily available or may be associated with long turnaround times can safely commence targeted treatments for benign upper GI conditions based primarily on endoscopic findings.
