Contemporary occurrence and aetiology of chronic leg ulcers in Africa: a systematic review and meta-analysis protocol.
Article in BMJ open, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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.
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
introductionChronic leg ulcers are known as a major and snowballing threat to public health and the global economy. In Africa, there is controversy on the dearth of studies reporting the epidemiology of chronic leg ulcers. The present systematic review and meta-analysis aim at synthesising the prevalence, incidence and aetiologies of this ailment in this continent from contemporary data. METHODS AND
designWe will include cohort studies, case-control, cross-sectional studies and case series with more than 30 participants. Electronical databases including African Journals Online, MEDLINE, Excerpta Medica Database and Web of knowledge, and grey literature will be searched for relevant abstracts of studies published and unpublished between 1 January, 2000, and 28 February, 2019, without language restriction. The review will be reported according to the Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. Each study included in this review will be assessed for methodological quality. Clinically homogenous studies will be pooled using random-effects meta-analysis. Visual inspection of funnel-plots and the Egger's test will be used to investigate publication bias. Meta-regression and subgroup analyses will be performed to investigate the possible sources of heterogeneity. ETHICS AND DISSEMINATION: The present study will be based on published data; therefore, ethical approval is not required. Result of the review will be presented at conferences, to relevant health authorities and will be published in a biomedical peer-reviewed journal. PROTOCOL REGISTRATION NUMBER: CRD42018108250.
