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
backgroundGuidelines recommend multiphasic computed tomography (CT) and/or contrast-enhanced magnetic resonance imaging (MRI) for the detection of hepatocellular carcinoma. The objectives of the study were to compare diagnostic parameters of non-contrast MRI against multiphase CT for diagnostic of hepatocellular carcinoma in patients who at risk of liver cancer considering Asia-Pacific clinical practice guidelines as the reference standard.
methodsMedical records of patients with chronic hepatic disease or have suspected liver cancer in surveillance of fewer than 100 days and underwent multiphasic CT, gadoxetic acid-enhanced MRI, and liver biopsy for diagnosis of liver cancer were included in analysis. Enhancement during the arterial phase and wash-out during a delayed phase or portal-venous considered as hepatocellular carcinoma in the multiphase CT. Mild-to-moderate hypersensitivity in imaging, presence of fat on out-of-phase imaging, non-enhancing capsule(s), mosaic appearance, hemorrhagic content, and/or nodule-in-nodule considered as hepatocellular carcinoma in MRI. Asia- Pacific clinical practice guidelines considered for biopsy/histopathology for detection of hepatocellular carcinoma.
resultsFor detection of hepatocellular carcinoma, non-contrast MRI had higher sensitivity (0.843 vs. 0.762, P < .001, q = 3.919) and accuracy (0.755 vs. 0.571, P < .001, q = 3.362) than the multiphase CT. While specificity was the same (0.864 vs. 0.809, P < .001, q = 2.584). Non-contrast MRI had 0-0.91 diagnostic confidence and multiphase CT had 0.49-0.81 diagnostic confidence for the detection of hepatocellular carcinoma.
conclusionsNon-contrast MRI easily facilitates the decision of chemotherapy and/or radiotherapy than multiphase CT in hepatocellular carcinoma.
