Potential of Gd-EOB-DTPA-enhanced MR imaging for evaluation of bile duct ligation-induced liver injury in rabbits.
Article in Hepatology international, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectivesThe aim of this study was to evaluate the potential of gadoxetic acid (Gd-EOB-DTPA)-enhanced MRI for assessment of bile duct ligation (BDL)-induced chelostatic liver injury in an animal model by T1 relaxation time measurements and first-pass perfusion analyses. MATERIALS AND
methodsTwenty-four rabbits were classified into three groups as follows: control group (N group), n = 8; BDL group studied on the 5th postoperative day (BDL-5d group), n = 8; BDL group studied on the 14th postoperative day (BDL-14d group), n = 8. A dual flip angle three-dimensional gradient echo sequence with volumetric interpolated breath-hold examination was performed before and at 20 min [hepatobiliary phase (HBP)] after Gd-EOB-DTPA administration. Besides, early dynamic contrast-enhanced MRI was performed for 4.32 min with a temporal resolution of 2.2 s. T1 relaxation times of liver parenchyma were measured and perfusion parameters were calculated.
resultsDilatation of intra-hepatic bile duct was found only in the BDL-14d group. HBP T1 relaxation times of the BDL-5d and BDL-14d groups were significantly prolonged (p < 0.001) and the enhancement slope percentage of BDL-5d and BDL-14d groups were significantly lowered in comparison with that of the N group (p < 0.001). There were no differences between the BDL-5d group and the BDL-14d group for HBP T1 relaxation times and the enhancement slope percentage (p > 0.05). Area under the receiver operating characteristic curve of HBP T1 relaxation time and the enhancement slope percentage for the selection of chelostatic liver were 0.98 and 0.92 for the BDL-5d group, and 0.96 and 0.98 for the BDL-14d group, respectively.
conclusionsHBP T1 relaxation time measurement in combination with first-pass enhancement slope percentage withhold promise to assess extrahepatic chelostatic liver injury.
