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
CatSper affects sperm function and male fertilization capacity markers, including sperm motility and egg penetration. The study has aimed to evaluate the mRNA expression of CatSper1, and CatSper3 in the spermatozoa of men with normozoospermia and Asthenoteratozoospermia, and to assess the correlation between genes expression and sperm parameters, fertilization rate, and embryo quality in intracytoplasmic sperm injection (ICSI). Reverse transcription-polymerase chain reaction was utilized to evaluate the mRNA expression of CatSper1 and CatSper3 in sperm in two patient groups: Normozoospermia (NOR; n = 32), and Asthenoteratozoospermia (AT; n = 22). In all patients receiving intracytoplasmic sperm injection, the fertilization rate and embryo quality were evaluated. CatSper1, and CatSper3 mRNA expression in sperm was significantly lower in AT males than in NOR (P < 0.05). Levels of these genes demonstrated a significant positive correlation with sperm motility, mitochondrial membrane potential (MMP), capacitation, fertilization rate, cleavage rate, and embryo quality (P < 0.05) following ICSI. However, a negative correlation was found between mRNA expression of CatSper1, 3 and sperm DNA fragmentation (P < 0.05). Findings indicate low levels of CatSper1 and CatSper3 mRNA expression in men with Asthenoteratozoospermia, which resulted in poor sperm quality and impaired embryo development following ICSI therapy.
