1 · What the graph read from it

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.

2 · The registry

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

backgroundFibrinogen is produced in the liver and tends to be reduced in liver cirrhosis. Quantitative and qualitative tests exist to measure fibrinogen. We aimed to validate the functional fibrinogen thromboelastography assay (FF-TEG) and propose a new model to estimate fibrinogen levels via the Clauss method (Clauss) using data from a prothrombin time-derived fibrinogen assay (PT-Fg) in patients with liver cirrhosis. MATERIALS AND

methodsClauss, PT-Fg, fibrinogen antigen (Fib-Ag) and FF-TEG were studied in 55 patients with liver cirrhosis (26 with Child-Turcotte-Pugh [CTP]-A disease, 14 with CTP-B and 15 CTP-C) and 20 healthy individuals.

resultsThe results of all four assays correlated strongly with each other, but gave significantly different mean levels in all cohorts. PT-Fg gave the highest levels whereas the Clauss gave the lowest levels. The FF-TEG performed well with results which were in between the Clauss and the PT-Fg. Significant differences were only observed between CTP-A and CTP-C for the Clauss, PT-Fg and Fib-Ag but not functional fibrinogen level. We devised a simple linear regression model in order to estimate Clauss from the PT-Fg. DISCUSSION: The results of the FF-TEG correlate well with those of routine fibrinogen assays in patients with liver cirrhosis. However, the FF-TEG assay does not discriminate between early and late stages of disease, pointing to a preserved fibrin clot strength in cirrhosis. Through linear regression models, fibrinogen levels can be accurately estimated using the Clauss method based on fibrinogen levels obtained in the cheaper PT-Fg.
