The structure of Shigella virus Sf14 reveals the presence of two decoration proteins and two long tail fibers.

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
Bacteriophage Sf14 infects the human pathogen Shigella flexneri. A previous low-resolution structure suggested the presence of a decoration protein on its T = 9 icosahedral capsid. Here, we determined high-resolution structures of the Sf14 capsid and neck, along with a moderate-resolution structure of the whole Sf14 tail and baseplate. These structures indicate the capsid has not one, but two different types of decoration proteins: a trimeric β-tulip lattice that covers the entire capsid and a set of Hoc-like proteins that bind preferentially to hexamers at the quasi-3-fold axes of symmetry. The neck also contains two sets of whiskers oriented in opposite directions, and the tail has two types of long tail fibers which may bind different receptors. Based on homology and phylogenetic analysis, Sf14 may be the product of multiple horizontal gene transfer events. The structures presented here can be used to investigate further hypotheses of phage structure-function relationships and structural diversity.
