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

Roles for long noncoding RNAs (lncRNAs) in gene expression are emerging, but regulation of the lncRNA itself is poorly understood. We have identified a homeodomain protein, AtNDX, that regulates COOLAIR, a set of antisense transcripts originating from the 3' end of Arabidopsis FLOWERING LOCUS C (FLC). AtNDX associates with single-stranded DNA rather than double-stranded DNA non-sequence-specifically in vitro, and localizes to a heterochromatic region in the COOLAIR promoter in vivo. Single-stranded DNA was detected in vivo as part of an RNA-DNA hybrid, or R-loop, that covers the COOLAIR promoter. R-loop stabilization mediated by AtNDX inhibits COOLAIR transcription, which in turn modifies FLC expression. Differential stabilization of R-loops could be a general mechanism influencing gene expression in many organisms.
