Effects of Recombinant Human Growth Hormone on the Onset of Puberty, Leydig Cell Differentiation, Spermatogenesis and Hypothalamic KISS1 Expression in Immature Male Rats.

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
purposeRecombinant human growth hormone (rhGH) has been used to treat short stature and rhGH-related syndromes. However, there are concerns that rhGH-treatment may cause precocious puberty. We investigated the effects of rhGH-treatment on the puberty onset, sexual maturation, androgen production, and hypothalamic gene expression in prepubertal male rats. MATERIALS AND
methodsSprague-Dawley male rats were injected subcutaneously daily with 1 or 2 IU/kg/d rhGH or 0.1 mL saline from postnatal day (PND) 21 to 30. At PND 31 bodyweight, reproductive organs weight, preputial separation, testis histology, circulating testosterone, and expression of testicular steroidogenic pathway genes and hypothalamic
resultsBy day 4 of injection bodyweights of rhGH groups were significantly higher than those of controls. rhGH 2 IU group showed earlier preputial separation compared to the control group. At PND 31, the weights of testes, epididymides, seminal vesicles, prostates, and preputial glands of the 2 IU-rhGH group were significantly higher than control group. Serum testosterone levels of the 2 IU-rhGH group were significantly higher than control group. Testicular steroidogenic pathway gene
conclusionsPrepubertal rhGH-treatment in male rats may induce early onset of puberty, sexual maturation, elevation of testosterone, and spermatogenesis, and accompanies downregulation of hypothalamic KISS1.
