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

G-quadruplexes (G4s) are noncanonical, four-stranded nucleic acid structures formed in guanine-rich regions that influence many biological processes, including transcription. We previously developed a yeast-based system to study the transcriptional modulation of p53 family proteins by G4-forming sequences (G4FS) using artificial constructs. Here, motivated by the observation of genome-wide enrichment of G4FS in proximity to p53 and NF-κB response elements (REs), we examined how native combinations of G4FS and REs derived from human promoters influence the activity of p53 or NF-κB family proteins. To this end, five pairs of isogenic reporter strains were developed, and the propensity of G4FS to adopt G4 structures was confirmed by
