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
Background: Cannabis and cannabinoids affect almost every system of the body and exert systemic effects such as alterations in memory and cognitive functions, neurotransmission impediment, as well as obstruction of endocrine and reproductive system functions. Reproduction is a complicated phenomenon that integrates biological, psychological and behavioural aspects, hence susceptible to intracellular and extracellular modulations by numerous chemicals and toxicants like cannabis. Aim: The effects of early-life exposure to cannabis on reproductive function biomarkers and genes were investigated in male and female Wistar rats in this study. Method: An initial computational analysis (molecular docking and induced fit docking) of some cannabinoids with reproductive enzymes; androgen and follicle stimulating hormone receptors was conducted. Overall, cannabichromene (CBC) had the best IFD scores and binding free energies for the two proteins studied and it interacted with notable amino acids within their active sites. Subsequently, forty (40) Wistar rats, 20 male and 20 female (24-28 days old, weighing 20-28 ± 2 g) were divided into two groups each and orally administered CBC for 21 days. Penile tissues, testes and ovaries, were collected for biochemical analysis (hormonal assays, enzyme activities, and metabolite concentrations), gene expressions, and histological evaluations. Results: Activities of arginase and phosphodiesterase-5 in the penile tissue were significantly increased, while nitric oxide and calcium levels were significantly (p < 0.05) decreased in the CBC-exposed groups relative to the control group. Semen analysis showed significantly more abnormalities and decreased concentration of spermatozoa in the CBC-exposed group compared to the control. Activities of 17β-hydroxysteroid dehydrogenase and cholesterol level were decreased in both testes and ovaries of CBC-exposed groups. Furthermore, levels of testosterone, progesterone, luteinizing, and follicle-stimulating hormones were reduced in the serum of CBC rats. Moreover, relative expressions of androgen receptor and follicle-stimulating hormone receptor genes were significantly downregulated in the CBC-exposed groups. Histological evaluations revealed lesions, tubular necrosis, and cellular congestions in both the testes and ovaries. Conclusion: This study suggests that pre-puberty exposure to cannabis modulates reproductive functions via cannabichromene inhibition of steroidogenesis, stimulation of erectile dysfunction (modulation of intermediates and enzymes of the endothelial nitric oxide synthase (eNOS) pathway in the penile tissue), and downregulation of the expressions of genes associated with reproduction.
