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
objectiveThis systematic review and meta-analysis aimed to estimate the prevalence of respiratory viruses among people with acute respiratory infections (ARI) in Sub-Saharan Africa.
methodsWe performed an electronic search through the PubMed, EMBASE, Medline, and Scopus databases to identify observational (cross-sectional and cohort), and randomized controlled trial studies published in English and French between January 2006, and December 2019. We used a random-effects meta-analysis to estimate the pooled prevalence of major respiratory viruses across studies. Heterogeneity (I2) was assessed via the chi-square test of Cochran’s Q statistic. A p-value < 0.05 was considered statistically.
resultsThis meta-analysis included 73 studies (199,393 participants). Human rhinovirus (HRV) was the most commonly detected virus at 21.2% (95% CI [16.76; 25.75]). The second predominant virus was respiratory syncytial virus (RSV) at 16% (95% CI [12.51; 19.59]), followed by human adenovirus (AdV) at 14.3% (95% CI [10.13; 18.57]), and influenza at 13.9% (95% CI [11.27; 16.62]). Other detected viruses included human parainfluenzavirus (HPIV) 8.9% (95% CI [6.08; 11.83]), human coronavirus (HCoV) 7.2% (95% CI [3.77; 10.67]), enterovirus (EV) 7% (95% CI [4.2; 9.81]), human metapneumovirus (HMPV) 4.6% (95% CI [3.53; 5.78]), and human bocavirus (HBoV) 4.1% (95% CI [1.99; 6.34]). Significant heterogeneity was observed across the overall prevalence and within subgroups for all viruses. Notable variations in respiratory virus prevalence were identified according to age, clinical presentation, setting, and Africa region.
conclusionThe present study has shown that HRV is the most common respiratory virus detected among ARI in Sub-Saharan Africa, followed by RSV, AdV, and influenza virus. Ongoing surveillance is important to monitor changes in the etiology, seasonality, and severity of pathogens of interest. CLINICAL TRIAL NUMBER: Not applicable.
