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
backgroundThe endosperm of rice (Oryza sativa) has been usually used for the study of starch synthesis. Although several related factors have been revealed, other unknown members remain to be identified, given that starch synthesis is a complicated and sophisticated process.
resultsHere, we identified and characterized a new rice seed mutant, floury endosperm14 (flo14), which showed chalked endosperm and seed-lethal phenotypes. Map-based cloning indicated FLO14 encodes a novel P-family PPR protein which contains ten PPR motifs. Afterwards the gene was named OsNPPR3. Subcellular localization showed OsNPPR3 was targeted to nucleolus. Quantitative RT-PCR analysis demonstrated that OsNPPR3 was universally expressed in various tissues, with pronounced levels during rice endosperm development. Molecular analysis further suggested that OsNPPR3 was involved in the regulation of expression levels and splicing of a few genes in mitochondria.
conclusionThe study demonstrates that the nucleolus-localized PPR protein is responsible for the flo14 mutant phenotypes through affecting nuclear and mitochondrial gene expression and splicing.
