Prevalence and associated factors of preterm birth in Ethiopia: systematic review and meta-analysis protocol.
Article in BMJ open, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
introductionPreterm birth (PTB) complications are the leading cause of death among neonates globally. The reduction in neonatal mortality is not remarkable in Ethiopia. Therefore, this review will assess the magnitude and associated factors of PTB in Ethiopia. METHODS AND ANALYSIS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline will be followed during the systematic review. We will include all observational studies published from 1 January 2009 to 31 December 2019 that examined the level and/or associated factors of any type of PTB among live births in Ethiopia. Inclusion criteria will be all live births, PTB defined as delivery before 37 weeks gestation. The primary outcome will be PTB <37 weeks, and secondary outcomes including PTB <34, <32 and <28 weeks will be analysed. PubMed and Science Direct databases as well as Google search engine and Google Scholar will be searched. The pooled prevalence of preterm and effect size of association for associated factors will be analysed using the Stata software V.14. The heterogeneity between studies will be measured by I ETHICS AND DISSEMINATION: No ethical approval is necessary for this systematic review. The findings will be published in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42017077356.
