Analysis of the different subpeptidomes presented by the HLA class I molecules of the B7 supertype.

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
MHC-I molecules of the HLA-B7 supertype preferentially bind peptides with proline at position 2. HLA-B*51:01 and B*51:08 present two predominant subpeptidomes, one with Pro2 and hydrophobic residues at P1, and another with Ala2 and Asp enriched at position 1. Here, we present a meta-analysis of the peptidomes presented by molecules of the B7 supertype to investigate the presence of subpeptidomes across different allotypes. Several allotypes presented subpeptidomes differing in the presence of Pro or another residue at P2. The Ala2 subpeptidomes preferred Asp1 except in HLA-B*54:01, where ligands with Ala2 contained Glu1. Sequence alignment and the analysis of crystal structures allowed us to propose positions 45 and 67 of the MHC heavy chain as relevant for the presence of subpeptidomes. Deciphering the principles behind the presence of subpeptidomes could improve our understanding of antigen presentation in other MHC-I molecules. Running title: HLA-B7 supertype subpeptidomes.
