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

introductionVenous thromboembolism (VTE) is among the three major causes of cardiovascular diseases worldwide after ischaemic heart disease and stroke. Knowledge on the global epidemiology of this condition is deficient in Africa. Accurate data are needed to evaluate the burden of VTE in Africa to design effective preventive and treatment strategies. This systematic review and meta-analysis aims to summarise epidemiological data on VTE in Africa and to evaluate the use of prophylaxis in African patients at risk of VTE. METHODS AND ANALYSIS: Medline, Embase, Scopus and African Journal Online will be searched for relevant abstracts of studies published between 1 January 1986 and 5 December 2016, without language restriction. After a screening of abstracts, study selection, data extraction and assessment of the risk of bias, we shall assess studies individually for clinical and statistical heterogeneity. Appropriate meta-analytic technics will then be used to pool studies judged to be clinically homogeneous. Funnel-plots analysis and Egger's test will be used to detect publication bias. Results will be presented by geographical region (Central, Eastern, Northern, Southern and Western Africa). This systematic review will be reported according to the Meta-analysis of Observational Studies in Epidemiology Guidelines. ETHICS AND DISSEMINATION: The current study will be based on published data, and thus ethics consideration is not required. This review is expected to provide relevant data to help in quantifying the magnitude of this disease in Africa. The final report of this study will be published in a peer-reviewed journal and the findings will be submitted to relevant health authorities. TRIAL REGISTRATION NUMBER: The protocol for this review has been published in the International Prospective Register of systematic reviews (http://www.crd.york.ac.uk/PROSPERO), registration number: PROSPERO CRD42017056253.
