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

The binding site of a monoclonal anti-L-amino acid antibody (anti-L-AA) was modeled using the program SWISS-MODEL. Docking experiments with the enantiomers of phenylalanine revealed that the antibody interacts with L-phenylalanine via hydrogen bonds and hydrophobic contacts, whereas the D-enantiomer is rejected due to steric hindrance. Comparison of the sequences of this antibody and an anti-D-amino acid antibody (anti-D-AA) indicates that both immunoglobulins derived from the same germline progenitor. Substitution of four amino acids residues, three in the framework and one in the complementarity determining regions (CDRs), allowed in silico conversion of the anti-L-AA into an antibody that stereoselectively binds D-phenylalanine.
