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

purposeTo review available evidence to assess the efficacy and safety of thrombolysis therapy for non-cirrhosis-related portal vein thrombosis (PVT) that has not improved with anti-coagulation.

methodsA literature search of databases MEDLINE, EMBASE, PUBMED, Cochrane and World Wide Web identified studies after 2000 utilizing portal vein thrombolysis in non-cirrhotic patients, with a minimum of 5 patients. Nine studies met criteria with 134 patients. The primary outcome evaluated was radiological re-canalization of the portal vein and symptomatic improvement post treatment. Secondary data points obtained included morbidity, mortality, thrombolysis approach and technique.

resultsThe re-canalization rate following thrombolysis was 84% (0.67-1.02 CI 95%) and the symptomatic improvement rate 86% (0.70-1.01 CI 95%). The major complication rate was 7% (0.01-0.14 CI 95%) and the overall complication rate 25% (0.08-0.41 CI 95%). The direct and systemic thrombolysis approach showed no significant re-canalization rates with an odds ratio of 0.78 (0.24-2.55 CI 95%, P = 0.68). Thrombectomy in conjunction with thrombolysis demonstrated no improved patency or symptom relief with an odds ratio of 1 (0.17-6.03 CI 95%, P = 1.00).

conclusionThrombolysis is an effective and safe therapy for portal vein thrombosis in non-cirrhotic patients where systemic anti-coagulation has failed. The heterogenicity of study thrombolysis protocols limits the evaluation of secondary outcomes, and future data should be standardized to determine the role of the thrombolysis access route and thrombectomy.
