Effectiveness of SARS-CoV-2 testing strategies: A scoping review.
Review in Cochrane evidence synthesis and methods, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
Introduction: Rapid identification of severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) infections by testing potentially reduced coronavirus disease-19 (COVID-19) cases. Testing strategies varied across countries and during different stages of the pandemic. This scoping review aims to map the available evidence on the effectiveness of SARS-CoV-2 testing strategies for suspected cases and asymptomatic populations to inform the development of World Health Organization recommendations for SARS-CoV-2 testing strategies. Methods: We followed the standard methods for scoping reviews. We searched Medline (OVID), EMBASE (Elsevier), and Europe PMC using a comprehensive search strategy. The search was conducted in January 2023 and covered the period from January 2020 to January 2023. Two review authors independently screened the titles and abstracts, and full texts. Data were extracted onto a pilot-tested form by a review author and cross-checked by another review author. We provided a descriptive report summarizing the extracted data around the outcomes and created an interactive map of the available evidence using the evidence for policy and practice mapper. Results: We identified 34,550 citations from the databases. After the screening, we included 17 studies from 11 countries for data extraction. The study designs were randomized controlled trials ( Conclusion: We identified evidence gaps in the effectiveness of SARS-CoV-2 testing strategies, particularly in specific settings such as schools and long-term care facilities. This scoping review provides a foundation for further research, allowing researchers and stakeholders to focus on addressing the identified gaps.
