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

Interactions between biomolecules govern cellular biology. While protein/protein and protein/nucleic acid (DNA, RNA) interactions-and, to a lesser extent, RNA/RNA and RNA/DNA interactions-have been extensively described, a question remains as to whether and how non-canonical DNA structures might interact with each other. This is of particular interest for guanine (G)-rich sequences that can fold into G-quadruplex (G4) structures: Individual G4s are currently studied for their involvement in a myriad of cellular events (mostly pertaining to the control of gene expression), and, more recently, the interactions between two G4s have been scrutinized as being part of a novel gene expression regulatory mechanism involving chromatin remodeling through G4-mediated loop formation. The question that needs to be answered is whether G4s or their corresponding G-rich sequences are involved. We present here a series of results collected using a combination of sequences, experimental conditions, and techniques, which led us to the conclusion that G4/G4 intermolecular interactions are mostly governed by primary sequence interactions in vitro.
