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

Immunodominance is defined as restricted responsiveness of T cells to a few selected epitopes from complex antigens. Strategies currently used for elucidating CD4(+) T cell epitopes are inadequate. To understand the mechanism of epitope selection for helper T cells, we established a cell-free antigen processing system composed of defined proteins: human leukocyte antigen-DR1 (HLA-DR1), HLA-DM and cathepsins. Our reductionist system successfully identified the physiologically selected immunodominant epitopes of two model antigens: hemagglutinin-1 (HA1) from influenza virus (A/Texas/1/77) and type II collagen (CII). When applied for identification of new epitopes from a recombinant liver-stage antigen of malaria falciparum (LSA-NRC) or HA1 from H5N1 influenza virus ('avian flu'), the system selected single epitopes from each protein that were confirmed to be immunodominant by their capacity to activate CD4(+) T cells from H5N1-immunized HLA-DR1-transgenic mice and LSA-NRC-vaccinated HLA-DR1-positive human volunteers. Thus, we provide a new tool for the identification of physiologically relevant helper T cell epitopes from antigens.
