Age of detection of congenital hearing loss in South Africa: A systematic review.
Review in Journal of public health in Africa, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Background: Newborn hearing screening is the most important step towards early intervention of congenital or early-onset hearing loss (HL) and has the potential to optimise patient outcomes. Yet, literature on the age of identification of this HL in South Africa (SA) is sparse. Aim: To determine the age of identification of congenital HL from published studies in SA. Setting: The study was conducted in SA. Methods: This was a systematic review conducted during April 2024 - June 2024 across the following databases: PubMed, EBSCO, Web of Science and Scopus. A random effects (RE) model meta-analysis was conducted using STATA version 18. Statistical tests conducted include meta-summary statistics and RE meta-analysis. Results: Ten studies, with a total of 1501 children, were included in this review. The computed Q-test of homogeneity was 5870.97 and the pooled mean age of identification was 30 months (95% confidence intervals [CI]: 19.3-41.3). Conclusion: These findings show that congenital or early-onset HL in SA is identified later than the national and international standards, that is, < 1 month of age. These findings are important for future research, priority setting and implementation of strategies to reduce the burden and impact of HL. Future research investigating the barriers to early detection of HL in SA is recommended. Furthermore, the implementation of evidence-based interventions to lower the age of identification of congenital HL to enable its early detection and intervention in this age group is recommended. Contribution: This study highlights the need to strengthen preventative programmes for paediatric HL in SA.
