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
Although chromosome set manipulation techniques including polyploidy induction and gynogentic induction in flatfish are becoming increasingly mature, there exists a poor understanding of their effects on embryonic development. PAX3 plays crucial roles during embryonic myogenesis and neurogenesis. In olive flounder (Paralichthys olivaceus), there are two duplicated pax3 genes (pax3a, pax3b), and both of them are expressed in the brain and muscle regions with some subtle regional differences. We utilized pax3a and pax3b as indicators to preliminarily investigate whether chromosome set manipulation affects embryonic neurogenesis and myogenesis using whole-mount in situ hybridization. In the polyploid induction groups, 94 % of embryos in the triploid induction group had normal pax3a/3b expression patterns; however, 45 % of embryos in the tetraploid induction group showed abnormal pax3a/3b expression patterns from the tailbud formation stage to the hatching stage. Therefore, the artificial induction of triploidy and tetraploidy had a small or a moderate effect on flounder embryonic myogenesis and neurogenesis, respectively. In the gynogenetic induction groups, 87 % of embryos in the meiogynogenetic diploid induction group showed normal pax3a/3b expression patterns. However, almost 100 % of embryos in the gynogenetic haploid induction group and 63 % of embryos in the mitogynogenetic diploid induction group showed abnormal pax3a/3b expression patterns. Therefore, the induction of gynogenetic haploidy and mitogynogenetic diploidy had large effects on flounder embryonic myogenesis and neurogenesis. In conclusion, the differential expression of pax3a and pax3b may provide new insights for consideration of fish chromosome set manipulation.
