Improved Culture Methods for Human Coronaviruses HCoV-OC43, HCoV-229E, and HCoV-NL63.
Article in Current protocols, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 11 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
HCoV-OC43, HCoV-229E, HCoV-NL63, and HCoV-HKU1 are four of the seven known human coronaviruses (HCoVs) and, unlike the highly pathogenic SARS-CoV, MERS-CoV, and SARS-CoV-2, these four so-called seasonal HCoVs generally cause mild upper-respiratory-tract illness. As Biosafety Level 2 (BSL-2) pathogens, the seasonal HCoVs are more accessible and can be used as surrogates for studying the highly pathogenic HCoVs. However, scientists have for many years found these difficult to study because of the lack of a universal culture system and the inability of typical culture methods to yield high-titer infectious stocks. We have developed assays to grow and quantify infectious virus and viral RNA for HCoV-OC43, -229E, and -NL63. We identified which immortalized cell lines should be used to optimize the replication of HCoV-OC43, -229E, and -NL63 in order to generate high titers (Vero E6, Huh-7, and LLC-MK2 cells, respectively). Here we present protocols for improved propagation and quantification of each seasonal HCoV. © 2023 Wiley Periodicals LLC.
