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
Somatic cell nuclear transfer (SCNT) or cloning technology is widely used in agriculture and biomedicine. However, the application of this technology is limited by the low developmental competence of cloned embryos or fetuses, which frequently exhibit abnormal development of trophoblast cells or placentas. The purpose of this study was to investigate the possible causes of the erroneous placental development of SCNT-derived pig fetuses. The placental transcriptomic and lipidomic profiles were compared between 30-day-old SCNT- and artificial insemination (AI)-produced pig fetuses. Differentially expressed lipid metabolites between two groups of placentas were selected to test their effects on porcine trophoblast cell activity. The results showed that SCNT placentas exhibit impaired lipid metabolism and function. The level of a metabolite, lysophosphatidylcholine (LPC), in the glycerophospholipid metabolism pathway was substantially increased in SCNT placentas, compared with AI placentas. The elevation in LPC content may lead to impaired placental development in cloned pig fetuses, as LPC inhibited the proliferation and migration of porcine trophoblast cells. This study discovers a main cause of erroneous development of cloned pig fetuses, which will be beneficial for understanding the regulation of SCNT embryo development, as well as developing new methods to improve the efficiency of pig cloning.
