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
Maternal sleep deprivation (SD) during pregnancy is prevalent and associated with adverse outcomes. However, the effect of SD on reproductive development in postpubertal male offspring remains incompletely understood. We investigated the effects of maternal SD during mid-gestation (gestational day 8 to delivery) and late gestation (gestational day 15 to delivery) on reproductive development in a 8-week-old male offspring of C57BL/6J mice. We analyzed the underlying oxidative stress mechanisms implicated in these effects. SD was induced for 16 h per day using the modified multiple platform method. Sperm parameters of the offspring ( n = 8 per group) were analyzed, including serum reproductive hormones (testosterone, follicle-stimulating hormone, and luteinizing hormone), testicular oxidative stress markers (superoxide dismutase and malondialdehyde), and key proteins in the phosphatidylinositol 3-kinase/protein kinase B/mammalian target of the rapamycin (PI3K/Akt/mTOR) signaling pathway. Among the offspring, the mid-gestation SD (MSD) group showed significantly lower sperm count, sperm motility, and follicle-stimulating hormone concentrations than the respective control groups (all P < 0.05). The late-gestation SD (LSD) group showed lower luteinizing hormone concentrations than the control group ( P < 0.05). Testosterone, follicle-stimulating hormone, and luteinizing hormone concentrations were lower in the MSD group than those in the LSD group (all P < 0.05). Superoxide dismutase activity was lower in the MSD group than that in the control group ( P < 0.05). No significant changes were observed in PI3K/Akt/mTOR pathway protein expression. In conclusion, maternal SD, particularly from mid-gestation to delivery, impairs spermatogenesis in postpubertal male offspring, which may be mediated through sex hormone dysregulation and testicular oxidative stress.
