Characterization of Lactococcus lactis phage 949 and comparison with other lactococcal phages.
Article in Applied and environmental microbiology, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 37 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
The virulent Lactococcus lactis phage 949 was isolated in 1975 from cheese whey in New Zealand. This phage is a member of the Siphoviridae family and of a rare lactococcal phage group that bears its name (949 group). It has an icosahedral capsid (79-nm diameter) and a very long noncontractile tail (length, 500 nm; width, 12 nm). It infected 7 of 59 tested L. lactis strains, a somewhat expanded host range for a rare lactococcal phage. The abortive phage infection defense mechanisms AbiQ and AbiT strongly inhibited the multiplication of phage 949, but AbiK and AbiV did not. Its double-stranded DNA (dsDNA) genome of 114,768 bp is, to date, the largest among lactococcal phages. Its GC content was calculated at 32.7%, which is the lowest reported for a lactococcal phage. Its 154 open reading frames (ORFs) share limited identity with database sequences. In addition, terminal redundancy was observed as well as the presence of six tRNAs, one group I intron, and putative recombinases. SDS-PAGE coupled with mass spectrometry identified 13 structural proteins. The genomes of the members of the 10 currently known L. lactis phage groups were used to construct a proteomic tree. Each L. lactis phage group separated into distinct genetic clusters, validating the current classification scheme. Of note, members of the polythetic P335 groups were clearly separated into subgroups.
