RAZOR: a database of PCR primers targeting human respiratory viruses.
Article in NAR genomics and bioinformatics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Respiratory viruses like SARS-CoV-2, Influenza A, and others represent a considerable threat to public health, infecting millions of people annually. Previous respiratory virus outbreaks have demonstrated the value of polymerase chain reaction (PCR) testing as a gold standard for definitive virus identification; however, existing database resources for viral PCR primer design are either outdated or restricted to a small number of species. To address the need for updated and comprehensive viral PCR resources, we introduce RAZOR, a database of nearly 20 000 primers covering 20 different respiratory virus species. We created genome-wide template sets for each virus and used them to design quantitative PCR (qPCR) and standard PCR primer pairs with Primer3. Detailed primer information, including sequence coordinates, melting and annealing temperatures, GC content, and hairpin structure probabilities, is provided through a user-friendly Integrative Genomics Viewer (IGV) interactive display. Validated primers, including a group of SARS-CoV-2 primers tested by our group, are also showcased in a dedicated section of the IGV. RAZOR stands out as a valuable tool for investigators designing targeted PCR approaches for respiratory virus detection. Database URL: https://razor-razor.webapps.iu.edu.
