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
The centromere is a key chromosomal component for sister chromatid cohesion and is the site for kinetochore assembly and spindle fiber attachment, allowing each sister chromatid to faithfully segregate to each daughter cell during cell division. It is not clear what types of sequences act as functional centromeres and how centromere sequences are organized in Oryza brachyantha, an FF genome species. In this study, we found that the three classes of centromere-specific CentO-F satellites (CentO-F1, CentO-F2, and CentOF3) in O. brachyantha share no homology with the CentO satellites in Oryza sativa. The three classes of CentO-F satellites are all located within the chromosomal regions to which the spindle fibers attach and are characterized by megabase tandem arrays that are flanked by centromere-specific retrotransposons, CRR-F, in the O. brachyantha centromeres. Although these CentO-F satellites are quantitatively variable among 12 O. brachyantha centromeres, immunostaining with an antibody specific to CENH3 indicates that they are colocated with CENH3 in functional centromere regions. Our results demonstrate that the three classes of CentO-F satellites may be the major components of functional centromeres in O. brachyantha.
