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
Using a synthetic DNA library coding for random 10-amino acid peptides (R10aPL), mRNA-display was applied to the isolation of interactive peptides using a monoclonal antibody against human TP53 (hTP53) as a model. Display molecules consisting of peptides and the nucleotide sequences encoding them were synthesized in vitro and subjected to four to five cycles of affinity selection. Thirty-four clones each isolated in the 4th or 5th round were sequenced. A core sequence, (X)-S-D-L-(Z)-K-L essential for binding was found, in which (X) and (Z), though undefined, were mostly F or Y and W, respectively. Although no peptides that fully matched with hTP53 were found in the clones isolated, the core sequence was found in hTP53. A 10-amino acid peptide containing the core sequence was chemically synthesized to verify its binding with SPR. Its Kd value for the antibody was 6 nM. The amino acids in epitopes essential for binding could be identified by mRNA-display with R10aPL.
