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
Seeds acquire primary dormancy during their development and the phytohormone abscisic acid (ABA) is known to play a role in inducing the dormancy. qSD12 is a major seed dormancy quantitative trait locus (QTL) identified from weedy rice. This research was conducted to identify qSD12 candidate genes, isolate the candidates from weedy rice, and determine the relation of the dormancy gene to ABA. A fine mapping experiment, followed by marker-assisted progeny testing for selected recombinants, narrowed down qSD12 to a genomic region of <75 kb, where there are nine predicted genes including a cluster of six transposon/retrotransposon protein genes and three putative (a PIL5, a hypothetic protein, and a bHLH transcription factor) genes based on the annotated Nipponbare genome sequence. The PIL5 and bHLH genes are more likely to be the QTL candidate genes. A bacterial artificial chromosome (BAC) library equivalent to 8-9 times of the haploid genome size was constructed for the weedy rice. One of the two BAC contigs developed from the library covers the PIL5 to bHLH interval. A pair of lines different only in the QTL-containing region of <200 kb was developed as isogenic lines for the qSD12 dormancy and non-dormancy alleles. The dormant line accumulated much higher ABA in 10-day developing seeds than the non-dormant line. In the QTL-containing region there is no predicted gene that has been assigned to ABA biosynthetic or metabolic pathways. Thus, it is concluded that the qSD12 underlying gene promotes ABA accumulation in early developing seeds to induce primary seed dormancy.
