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
backgroundIrreversible transmural intestinal necrosis (ITIN) is associated with high mortality rates in patients with acute occlusive mesenteric ischemia (AOMI). Currently, there are not many studies on the use of dual energy computed tomography (DECT) for evaluating ITIN.
aimTo evaluate the diagnostic value of DECT for ITIN in AOMI.
methodsThe cases and computed tomography (CT) images of 102 patients with clinically diagnosed AOMI (including 48 ITIN) from January 2012 to January 2022 were retrospectively collected. The CT scans included both multidetector CT and DECT. The raw data from DECT portal-venous phase were reconstructed into 120 kVp mixed energy image, 50 keV virtual monoenergetic imaging, and iodine map. Two radiologists independently completed the subjective visual assessment of CT signs related to AOMI. Objective parameters, including the attenuation of the normal and lesion intestinal wall segment (CT
resultsRegarding subjective signs, logistic regression analysis revealed reduced or absent bowel wall enhancement [odds ratio (OR) = 5.576, 95% confidence interval (CI): 1.547-20.093], bowel dilation (OR = 11.613, 95%CI: 3.790-35.586), and parenchymatous organ infarction (OR = 4.727, 95%CI: 1.536-14.551) were independent risk factors for the ITIN. CT subjective signs had a high diagnostic efficacy for ITIN (AUC = 0.853). The two DECT objective parameters also exhibited excellent diagnostic value for ITIN, with an AUC of 0.79, a cut-off value of CT
