Assessing the Accuracy of Contrast-Enhanced CT Abdomen in Identifying and Stratifying Risk of Oesophageal Varices in Cirrhotic Patients: A Retrospective Study.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeOesophagogastroduodenoscopy (OGD) is the current standard for diagnosing and grading oesophageal varices (OV), but it is invasive and costly. This study retrospectively evaluated how well contrast-enhanced computed tomography (CT) scans of the abdomen perform in detecting and assessing the risk level of OV compared to OGD.
methodsThe study analyzed 92 cases of patients with liver cirrhosis who underwent contrast-enhanced CT within three months of having an OGD. Two experienced radiologists measured the largest OV diameter on CT images, which was then compared to OV grading from the OGD. Patient demographics, underlying causes of cirrhosis, and liver function classification were also reviewed.
resultsDetection rates of varices by the two radiologists were moderate, with a combined sensitivity under 70%. For mild varices, CT showed moderate sensitivity and specificity but low detection rates. For moderate and severe varices, CT sensitivity and specificity varied, with overall accuracy just over 50%. There was no clear correlation between varix size on CT and variceal grade on OGD.
conclusionContrast-enhanced CT has limited accuracy in detecting and grading OV compared to OGD, highlighting that OGD remains the preferred method for OV evaluation in patients with cirrhosis.
