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

MAIN

conclusionRepeat-length expansion generates stable, predominantly parallel G4 structures from TTGGG repeats in vitro, identifying expanded plant mitochondrial loci as candidate non-B-DNA-prone regions whose in vivo function remains unresolved. G-quadruplexes (G4s) are non-canonical DNA structures formed by stacked guanine tetrads stabilized by Hoogsteen base pairing and monovalent cations. Although G4s have been extensively studied in nuclear genomes and telomeric DNA, much less is known about G-rich tandem repeats with G4-forming potential in organellar genomes. Here, we investigated exact TTGGG tandem repeats in plant mitochondrial genomes and asked whether repeat expansion can generate local G4-compatible sequence architectures. We first used the exact (TTGGG)
