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

backgroundCentral nervous system (CNS) tumors pose a substantial health problem. Although data on specific time periods and regions of Africa have been previously reported, no study has yet to provide a systematic review of CNS tumors for the entire continent of Africa. This study aims to analyze the frequency of CNS tumors in Africa from 1960 to 2017.

methodsA comprehensive literature search on CNS tumors in Africa was performed using multiple online scientific databases. The following keywords were queried in combination with the phrase "CNS tumors in Africa": incidence, frequency, epidemiology, prevalence, brain, and cancer. A total of 26 articles met the inclusion criteria. Each selected article reported incidence and mortality rates from different regions of Africa in a time period between 1960 and 2017. SPSS21 statistical software was used to analyze the data.

resultsNigeria, Egypt, and Uganda were found to have the most of the cases of CNS tumors in Africa. Males made up 54% of the 5902 cases per 100 000 population. The most common CNS tumors found were astrocytoma (24.70%), meningioma (22.22%), pituitary adenoma (8.4%), medulloblastoma (4.26%), craniopharyngioma (4.07%), and other not specified (25.17%).

conclusionsGiven the large population of Africa, the total reported cases may be underestimated when compared with other continents due to the lack of a central brain tumor registry in Africa. A comprehensive knowledge of CNS tumors in Africa is critical to population-based research and improving the current healthcare system.
