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

backgroundLiver fibrosis can progress to cirrhosis, hepatocellular carcinoma, or liver failure. Unfortunately, the antifibrotic agents are limited. Thrombin activates hepatic stellate cells (HSCs). Therefore, we investigated the effects of a direct thrombin inhibitor, dabigatran, on liver fibrosis.

methodsAdult male Sprague-Dawley rats were injected intraperitoneally with thioacetamide (TAA, 200 mg/kg twice per week) for 8 or 12 weeks to induce liver fibrosis. The injured rats were assigned an oral gavage of dabigatran etexilate (30 mg/kg/day) or vehicle in the last 4 weeks of TAA administration. Rats receiving an injection of normal saline and subsequent oral gavage of dabigatran etexilate or vehicle served as controls.

resultsIn the 8-week TAA-injured rats, dabigatran ameliorated fibrosis, fibrin deposition, and phosphorylated ERK1/2 in liver, without altering the transcript expression of thrombin receptor protease-activated receptor-1. In vitro, dabigatran inhibited thrombin-induced HSC activation. Furthermore, dabigatran reduced intrahepatic angiogenesis and portal hypertension in TAA-injured rats. Similarly, in the 12-week TAA-injured rats, a 4-week treatment with dabigatran reduced liver fibrosis and portal hypertension.

conclusionsBy inhibiting thrombin action, dabigatran reduced liver fibrosis and intrahepatic angiogenesis. Dabigatran may be a promising therapeutic agent for treatment of liver fibrosis.
