1 · What the graph read from it

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.

2 · The registry

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

This study aimed to evaluate the application of synthetized porcine follicle-stimulating hormone (spFSH) in combination with synthetized human chorionic gonadotropin (shCG) in inducing puberty in gilts, promoting estrus and ovulation in multiparous sows, and improving reproductive performance. In gilts, treatment with 30 µg spFSH + 150 IU shCG advanced the onset of puberty to 160 ~ 175 days of age in 76.62% of gilts, with a significantly lower incidence of ovarian cysts compared to PMSG and PG600. Hormonal profiling demonstrated that the applied protocol successfully induced endocrine maturation in gilts to levels consistent with those characteristic of natural puberty. In multiparous sows, the estrus-inducing effect of 30 µg spFSH + 150 IU shCG was comparable to PMSG and PG600 (400 IU PMSG and 200 IU hCG), while the incidence of ovarian cysts was significantly lower than in the PG600 group. This treatment significantly increased total piglets born per litter and reduced the number of days each piglet requires to be raised by a sow. When 300 IU shCG was used for ovulation induction, the farrowing rate significantly increased, and the number of days each piglet requires to be raised by a sow were further reduced. Hormonal analysis revealed that this treatment achieved physiological regulation of progesterone (P
