Value of CT findings to predict surgical ischemia in small bowel obstruction: A systematic review and meta-analysis.
Synthesis in European radiology, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04880421 (Diagnostic Performance of Arterial Time for CT Assessment of Parietal Enhancement Defect for the Diagnosis of Ischemia in Mechanical Small Bowel Occlusions), which is not on this map. Cited by 68 papers, 3 of them syntheses that pooled it.
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.

Abstract
purposeOur aim was to assess the diagnostic performance in determining strangulation in small bowel obstruction (SBO) for five CT findings commonly considered in published small bowel obstruction (SBO) management guidelines. MATERIALS AND
methodsMedical databases were searched for "bowel obstruction", "computed tomography", "strangulation", and related terms. Two reviewers independently selected articles for CT findings investigated with surgical or histological reference standards for strangulation. Bivariate random-effects meta-analytical methods were used.
resultsA total of 768 patients, including 205 with strangulation from nine studies, were evaluated. The reduced bowel wall enhancement CT sign had the highest specificity (95 %, CI 75-99), with a positive LR of 11.07 (2.27-53.88) and DOR of 22.86 (4.99-104.61). The mesenteric fluid sign had the highest sensitivity (89 %, CI 75-96) with a negative LR of 0.16 (0.07-0.39) and a DOR of 13.9 (5.73-33.75). The bowel wall thickness had a sensitivity of 48 % (CI 41-54), a specificity of 83 % (CI 74-89), a positive LR of 2.84 (1.83-4.41) and a negative LR of 0.62 (0.53-0.72). The other CT findings had lower diagnostic performance.
conclusionTwo CT findings should be used in clinical practice: reduced enhanced bowel wall is highly predictive of ischemia, and absence of mesenteric fluid is a reliable finding to rule out strangulation. KEY POINTS: • Reduced bowel wall enhancement on CT increases the probability of strangulation 11-fold. • Absence of mesenteric fluid on CT decreases the probability of strangulation 6-fold. • The clinical reliability of other CT signs is doubtful for predicting strangulation.
