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

Background: Physiologically, the spermatozoa are exposed to reactive oxygen species (ROS), and those ROS can strongly affect sperm's function through sperm capacitation. However, producing a high level of ROS reduces the sperm anti-oxidation system that may cause infertility, especially in cases with normal sperm count. Purpose: To investigate the expression of the CYP24A1 gene in human spermatozoa and other oxidation-related biomarkers, including vitamin E, ROS, and catalase as added tools to predict male infertility. Method: The study included 50 infertile men and 50 young volunteers from the general Iraqi population. Blood samples were drawn from all included men, and semen samples were collected by masturbation. All the samples of semen were investigated for CYP24A1 expression, and routine semen analysis was performed. In addition, the serum was separated and used to assess other biochemical parameters, namely catalase, reactive oxygen species, and vitamin E, which were measured by ELISA. Results: Serum ROS levels were higher in patients than control groups, while the serum catalase and vitamin E levels were significantly lower in patients than controls. CYP24A1 gene expression is significantly higher in infertile men with sperm count higher than 70 million and reaches twofold times the control. Conclusion: CYP24A1 gene expression is significantly higher in infertile men and can be used as a marker of infertility, especially in infertile males with normal sperm count. At the same time, the serum catalase and vitamin E levels were significantly lower, which can be added as tools to predict male infertility..
