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.
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
Retrotransposons consist of significant portions of many complex eukaryotic genomes and are often enriched in heterochromatin. The centromeric retrotransposon (CR) family in grass species is colonized in the centromeres and highly conserved among species that have been diverged for >50 MY. These unique characteristics have inspired scientists to speculate about the roles of CR elements in organization and function of centromeric chromatin. Here we report that the CRR (CR of rice) elements in rice are highly enriched in chromatin associated with H3K9me2, a hallmark for heterochromatin. CRR elements were transcribed in root, leaf, and panicle tissues, suggesting a constitutive transcription of this retrotransposon family. However, the overall transcription level was low and the CRR transcripts appeared to be derived from relatively few loci. The majority of the CRR transcripts had chimerical structures and contained only partial CRR sequences. We detected small RNAs (smRNAs) cognate to nonautonomous CRR1 (noaCRR1) and CRR1, but not CRR2 elements. This result was also confirmed by in silico analysis of rice smRNA sequences. These results suggest that different CRR subfamilies may play different roles in the RNAi-mediated pathway for formation and maintenance of centromeric heterochromatin.
