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
Parental transcript legacy plays an important role in fertilization and development of the early embryo. Parental environmental exposure affects the fertilization of eggs, but the underlying biochemical mechanism is largely unresolved. In this study, the parental environmental effects on fertilization of eggs were explored in the silkworm Bombyx mori (B. mori), an ideal lepidopteran animal model. The results showed that the rate of fertilization decreased after the parents were exposed to a poor environment at 32 °C with continuous illumination for 72 h on days 6-9 of the pupal stage, which is a key period for germ cell maturation. This was likely attributable to lower energy charge values, obstructed nicotinamide adenine dinucleotide (NAD(+)) regeneration and inactive tricarboxylic acid cycle (TCA), leading to accumulation of large amounts of pyruvic acid and lactic acid. This effect was related to energy metabolism via glycolysis; in particular disruption of pyruvate metabolism. In conclusion, this study showed parental exposure to an abnormal environment during germ cell maturation affected glycolysis and the subsequent fertilization of eggs via the parental transcript legacy in B. mori.
