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

objectivesTo estimate the overall and subgroup prevalence of otitis media with effusion (OME) in Africa, and identify setting-specific predictors in children and adults.

methodsPubMed, African Journals Online, African Index Medicus, Afrolib, SciELO, Embase, Scopus, Web of Science, The Cochrane Library, GreyLit and OpenGray were searched to identify relevant articles on OME in Africa, from inception to December 31st 2019. A random-effects model was used to pool outcome estimates.

resultsOverall, 38 studies were included, with 27 in meta-analysis (40 331 participants). The overall prevalence of OME in Africa was 6% (95% CI: 5%-7%;

conclusionOME prevalence was similar to that reported in other settings, notably high-income temperate countries. Health care providers should consider age, presence of cleft palate, adenoid hypertrophy and allergic rhinitis when assessing OME in children and deciding on a management plan. More research is required to confirm risk factors and evaluate treatment options. LEVEL OF EVIDENCE: 3a.
