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
During sexual propagation of primary trisomic 8, chromosome 8 breaks in some rice plants, resulting in a telotrisomic (2n+.8S) line. In this study, we observed that the extra short arm of chromosome 8 (.8S) can easily be lost in the telotrisomic, and we determined by fluorescence in-situ hybridization (FISH) analysis that the centromeric region of the extra .8S did not contain the rice centromeric satellite repeat (CentO) and centromere-specific retrotransposon (CRR); however, the extra .8S contained part of the CentO and CRR sequences in the initially preserved telotrisomic line. We confirmed by real-time quantitative PCR (RQ-PCR) analysis that the original functional centromere of the extra .8S was lost. Using both FISH and RQ-PCR, the breakage point of the extra .8S was found within the BAC clone a0070J19 sequence containing the first part of the short arm near the centromere region of chromosome 8 but without any CentO or CRR sequences. However, part of the DNA sequence within the a0070J19 BAC clone played a role in the new functional centromere, contributing to the morphological variations by asexually propagated plants of rice telotrisomics in the field. We conclude that CENH3, a key element in the eukaryotic kinetochore, may not always bind properly with the new functional centromere, resulting in loss of the extra .8S during mitosis and the chromosome numbers returning to diploid levels in subsequent generations.
