A new solid matrix for preservation of viral nucleic acid from clinical specimens at ambient temperature.
Article in Journal of virological methods, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Stabilizing paper matrix methods for retaining nucleic acid from inactivated clinical specimens offer a solution for molecular diagnostics when specimens may be stored or shipped at ambient temperature. We developed cellulose disks (UNEXP) saturated with a total nucleic acid extraction buffer (UNEX) modified from a previously developed lysis buffer for multiple enteric pathogens. Infectivity of hepatitis A virus, adenovirus and poliovirus was destroyed after 2-3 h incubation at room temperature on the UNEXP disks. Norovirus RNA could be detected in UNEXP-eluted nucleic acids by reverse transcription-quantitative PCR (RT-qPCR) from 54 stool samples after 2 weeks storage at room temperature on disks; a subset of seven samples were positive after 3 months storage. Genotyping was successful in 76% of 54 samples tested including six of seven samples stored on the UNEXP disks for up to one month. Comparison of UNEXP with the FTA elute card in a subset of 10 samples demonstrated similar detection and genotyping rates after two weeks of storage at room temperature. UNEXP disks could be useful for epidemiologic investigations of disease outbreaks in resource-limited areas by simplifying specimen transport to regional diagnostic laboratories or shipment to international centers without the need to ship samples on dry ice.
