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

Mutational changes that mostly occur at the head region of hemagglutinin (HA) lead to the emergence of new epidemic influenza viruses, whereas HA antigens have been modified to generate broadly neutralizing antibodies toward highly conserved epitopes in the HA stem. Interestingly, a recent analysis of serum antibody repertoires showed that broadly neutralizing antibodies bind to HA monomer at a conserved region occluded at the intermonomer interface of HA trimer and confer protection in animal models. We showed previously that the recombinant HA ectodomain from a pandemic strain A/Korea/01/2009 was monomeric in solution and crystal structure. In order to examine the potential antigenicity of a monomeric form, we designed HA monomer that incorporates mutations to destabilize trimer conformations. Starting with the HA trimer from a seasonal strain A/Thailand/CU44/2006, mutations were introduced at the intermonomer interface, Ser199 of HA1 and Gly47, Arg75, Phe88, Val91, and Arg106 of HA2. Two mutants, F88E and V91W, were characterized to form a monomer and their double mutant F88E/V91W monomer was selected as an antigen. Animal studies showed that the HA monomer induced protective immunity in vivo, comparable to the trimer, albeit low antibody titers in sera.
