1 · What the graph read from 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.

2 · The registry

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

Haemophilus influenzae is an important human pathogen that initiates infection by colonizing the upper respiratory tract. The H. influenzae Hia autotransporter is an adhesive protein that promotes adherence to respiratory epithelial cells. Hia adhesive activity resides in two homologous binding domains, called HiaBD1 and HiaBD2. These domains interact with the same host cell receptor, but bind with different affinities. In this report, we describe the crystal structure of the high-affinity HiaBD1 binding domain, which has a novel trimeric architecture with three-fold symmetry and a mushroom shape. The subunit constituents of the trimer are extensively intertwined. The receptor-binding pocket is formed by an acidic patch that is present on all three faces of the trimer, providing potential for a multivalent interaction with the host cell surface, analogous to observations with the trimeric tumor necrosis factor superfamily of proteins. Hia is a novel example of a bacterial trimeric adhesin and may be the prototype member of a large family of bacterial virulence proteins with a similar architecture.
