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

Portal hypertension is responsible for the bulk of the morbidity and mortality in patients with cirrhosis. Drug therapy to reduce portal pressure involves targeting two vascular beds. The first approach is to reduce intra hepatic vascular tone induced by the activity of powerful vasocontrictors such as angiotensin II, endothelin-1 and the sympathetic system and mediated via contraction of perisinusoidal myofibroblasts and pervascular smooth muscle cells. The second approach is to reduce mesenteric and portal blood flow. Non-selective β-blockers are widely used and have been shown to prolong patient survival and reduce oesophageal variceal bleeding in advanced cirrhosis. However many patients are unable to tolerate these drugs and they are ineffective in a significant proportion of patients. Unfortunately there are no other drug therapies that have proven efficacy in the treatment of portal hypertension and prevention of variceal bleeding. This review briefly outlines current therapeutic approaches to the management of portal hypertension, and the evidence supporting the role of the renin angiotensin system (RAS) and the use of RAS blockers in this condition. It will also outline recent advances in RAS research that could lead to the development of new treatments focusing in particular on the recently discovered "alternate axis" of the RAS.
