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

T40214 (STAT) and its recently investigated analogue STATB are G-quadruplex (G4) forming aptamers characterized by an unusually high percentage of C. The therapeutic potential of T40214 relies on its ability to inhibit the signalling pathway of STAT3, a protein frequently overexpressed in tumor cells. STAT adopts a dimeric 5'-5' end-stacked quadruplex structure, characterized by parallel strands, three G-tetrads and three propeller-shaped loops formed by a cytidine residue. STATB folds in a very similar structure, apart from an additional cytidine bulge loop. Many studies suggest that thermal stability and topology of G4 can be significantly affected by C methylation, thus resulting in altered interaction of G4-binding proteins with these structures. Considering this, two series of STAT and STATB analogues containing a single 5-methyl-2'-deoxycytidine (
