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

backgroundInfertility is a practical concern of Africans due to social disgrace and exclusion. This meta-analysis aims to analyze the proportion of primary and secondary infertility and identify the etiologic factors based on the studies conducted in Africa.

methodsAn internet-based search was conducted on the following databases; PubMed/Medline, EMBASE, Cochrane library, and google scholar. Both population and institution-based studies conducted among African couples, males, and females were included. Data extraction and critical appraisal of the articles were done by two independent investigators. Meta-analysis using a random effect model was conducted by Stata version 14. Forest plot, heterogeneity test, and funnel plot for publication bias were performed.

resultsThe pooled proportion of primary and secondary infertility in Africa was 49.91% (I

conclusionsIn Africa, the proportion of primary and secondary infertility is approximately equal. Infertility is mostly due to female-related causes like; pelvic inflammatory diseases, uterine tube related problems, and abortion. Oligospermia, asthenozoospermia, and varicocele were the commonest causes of male-related infertility. It is suggested that interpretation and utilization of these findings should consider the presence of substantial heterogeneity between the included studies.
