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

purposeThis study was performed to evaluate and compare threshold sperm parameters and sperm DNA fragmentation index (DFI), and further analyzed whether sperm DFI could be predicted from sperm parameters in men with varicocele. MATERIALS AND

methodsA total of 157 semen samples underwent both semen analysis and sperm DNA fragmentation (SDF) testing in men with varicocele. Sperm parameters were assessed using the World Health Organization guidelines. SDF testing was performed using the Halosperm kit. Sperm parameters and sperm DFI results were compared.

resultsThe overall sperm parameter results and sperm DFI showed normal values; however, the morphology value was at the lower limit of normal. High sperm DFI was associated with significantly lower motility and viability (p<0.001, respectively). Sperm motility and morphology were significantly higher in the higher sperm count group compared to the lower sperm count group (p<0.05), while sperm DFI was higher in the lower sperm count group (p<0.05). Sperm count and viability and sperm DFI were significantly associated with the quality of sperm motility (p<0.001). Sperm motility and sperm DFI were significantly different (p<0.001) between normal and abnormal sperm viability groups. Between normal and abnormal sperm morphology groups, sperm count, motility, and sperm DFI showed significant differences (p<0.001).

conclusionsIn this study, a correlation between SDF and sperm parameters was confirmed in men with varicocele. SDF may be contributing factors to sperm motility, viability, and morphology. Abnormal sperm count, motility, and viability showed high sperm DFI. Therefore, lower sperm parameters were indicative of increasing SDF in men with varicocele.
