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
Meiosis is essential for eukaryotic sexual reproduction and plant fertility. In comparison with over 80 meiotic genes identified in Arabidopsis, there are only ~30 meiotic genes characterized in rice (Oryza sativa L.). Many genes involved in the regulation of meiotic progression remain to be determined. In this study, we identified a sterile rice mutant and cloned a new meiotic gene, OsBVF1 (Bivalent Formation 1) by map-based cloning. Molecular genetics and cytological approaches were carried out to address the function of OsBVF1 in meiosis. Phylogenetic analyses were used to study the evolution of OsBVF1 and its homologs in plant species. Here we showed that the bvf1 male meiocytes were defective in formation of meiotic double strand break, thereby resulting in a failure of bivalent formation in diakinesis and unequal chromosome segregation in anaphase I. The causal gene, OsBVF1, encodes a unique OmpH/coiled-coil motif-containing protein and its homologs are highly conserved in the plant kingdom and seem to be a single-copy gene in the majority of plant species. Our study demonstrates that OsBVF1 is a novel plant-conserved factor involved in meiotic recombination in rice, providing a new insight into understanding of meiotic progression regulation.
