The utility of albumin-bilirubin score in patients with intrahepatic cholestasis of pregnancy: a retrospective comparative study.

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
objectiveThe aim of this study was to examine the utility of the albumin-bilirubin score in cases of intrahepatic cholestasis of pregnancy.
methodsA total of 413 patients (182 intrahepatic cholestasis of pregnancy, 50 suspected intrahepatic cholestasis of pregnancy, 181 healthy controls) enrolled in this study. Patients with typical pruritus and bile acid levels >10 μmol/L are defined as the intrahepatic cholestasis of pregnancy group. Patients with pruritus have the same pattern as intrahepatic cholestasis of pregnancy, but who are ultimately diagnosed with other dermatoses of pregnancy are defined as suspected intrahepatic cholestasis of pregnancy. Demographic data, laboratory parameters, and albumin-bilirubin scores were compared between three groups. Correlation analysis was performed on the albumin-bilirubin score and bile acid levels. Also, receiver operating curve analyses were performed to evaluate the predictive performance of the albumin-bilirubin score for intrahepatic cholestasis of pregnancy diagnosis.
resultsThe albumin-bilirubin score of the intrahepatic cholestasis of pregnancy group was significantly higher than the other groups. A positive, weak correlation was found between the albumin-bilirubin score and bile acid levels in the intrahepatic cholestasis of pregnancy group. The receiver operating curve curve analyses showed albumin-bilirubin score has significant performance for the prediction of intrahepatic cholestasis of pregnancy in all subjects (area under the curve: 0.726, 95%CI 0.679-0.774, p<0.001) (sensitivity: 69%, specificity: 64%). The detection rate for albumin-bilirubin score was calculated as 67.3%. The positive predictive value was 3.95% (CI 2.9-5.3%), and the negative predictive value was 98.9% (CI 98.6-99.2%).
conclusionThis study indicated higher albumin-bilirubin score levels in the intrahepatic cholestasis of pregnancy group and a positive relationship between serum bile acid levels and albumin-bilirubin score. Therefore, albumin-bilirubin score could be a cost-effective liver function test for pregnant women with intrahepatic cholestasis of pregnancy.
