Relationship between encephalopathy and portal vein-vena cava shunt: value of computed tomography during arterial portography.
Trial report in World journal of gastroenterology, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03453580 (Role of Multi Slice Computed Tomography Portography in Grading of Liver Cirrhosis), which is not on this map. Cited by 1 paper.
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.

Abstract
aimTo assess the value of computed tomography during arterial portography (CTAP) in portal vein-vena cava shunt, and analysis of the episode risk in encephalopathy.
methodsTwenty-nine patients with portal-systemic encephalopathy due to portal hypertension were classified by West Haven method into grade I(29 cases), grade II(16 cases), grade III(10 cases), grade IV( 4 cases). All the patients were scanned by spiral-CT. Plane scans, artery phase and portal vein phase enhancement scans were performed, and the source images were thinly reconstructed to 1.25 mm. We reconstructed the celiac trunk, portal vein, inferior vena cava and their branches and subjected them to three-dimensional vessel analysis by volume rendering (VR) technique and multiplanar volume reconstruction (MPVR) technique. The blood vessel reconstruction technique was used to evaluate the scope and extent of portal vein-vena cava shunt, portal vein emboli and the fistula of hepatic artery-portal vein. The relationship between the episode risk of portal-systemic encephalopathy and the scope and extent of portal vein-vena cava shunt, portal vein emboli and fistula of hepatic artery- portal vein was studied.
resultsThe three-dimensional vessel reconstruction technique of spiral-CT could display celiac trunk, portal vein, inferior vena cava and their branches at any planes and angles and the scope and extent of portal vein-vena cava shunt, portal vein emboli and the fistula of hepatic artery- portal vein. In twenty-nine patients with portal-systemic encephalopathy, grade I accounted for 89.7% esophageal varices, 86.2% paragastric varices; grade II accounted for 68.75% cirsomphalos, 56.25% paraesophageal varices, 62.5% retroperitoneal varices and 81.25% dilated azygos vein; grade III accounted for 80% cirsomphalos, 60% paraesophageal varices, 70% retroperitoneal varices, 90% dilated azygos vein, and part of the patients in grades II and III had portal vein emboli and fistula of hepatic artery-portal vein; grade IV accounted for 75% dilated left renal vein, 50% paragallbladder varices, all the patients had fistula of hepatic artery- portal vein.
conclusionThe three-dimensional vessel reconstruction technique of spiral-CT can clearly display celiac trunk, portal vein, inferior vena cava and their branches at any planes and angles and the scope and extent of portal vein-vena cava shunt. The technique is valuable for evaluating the episode risk in portal-systemic encephalopathy.
