Was Hypervascular Hepatocellular Carcinoma Visible on Previous Gadoxetic Acid-Enhanced Magnetic Resonance Images?
Article in Liver cancer, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundDuring the follow-up of patients with chronic liver disease, hypervascular hepatocellular carcinomas (HCCs) can develop either from pre-existing high-risk nodules or by de novo hepatocarcinogenesis. The purpose of this study was to evaluate, by retrospective analysis, the detectability and signal intensity on previous hepatocyte-phase gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging (EOB-MRI) of hypervascular HCC initially detected on current EOB-MRIs.
methodsWe examined 50 initially detected hypervascular HCCs that showed typical enhancement features on EOB-MRI in 39 patients whose previous EOB-MRI images obtained 6-19 months earlier were available. The detectability of each hypervascular HCC on the hepatocyte phase images of previous EOB-MRIs was assessed. The imaging features on hepatocyte-phase images of previous EOB-MRIs at the locations where hypervascular HCCs were found on the current EOB-MRI images were classified as detectable or undetectable. The signal intensities of detectable nodules (defined as group A) on hepatocyte-phase images of previous EOB-MRIs were classified as hypo-, iso-, or hyperintensity. Nodules undetectable on the hepatocyte-phase images of previous EOB-MRIs were assigned to group B.
resultsTwenty-two (22/50, 44%) hypervascular HCCs were detectable on the earlier hepatocyte phase images (group A). In contrast, 28 (28/50, 56%) hypervascular HCCs were not detectable on the hepatocyte phase of earlier EOB-MRI images (group B).
conclusionWhen the previous EOB-MRI images were used as the reference, more than half (28/50, 56%) of hypervascular HCCs initially appearing on the current EOB-MRI images were found not to have developed from nodules detectable on the previous MRIs through the traditionally accepted process of multistep carcinogenesis. Instead, they seemed to have developed via an "imaging-occult" process of carcinogenesis in patients with chronic liver diseases.
