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

objectiveHuman sperm parameters varies widely among men and even between consecutive samples in the same individual with respect to their concentration, motility, morphology, and DNA fragmentation. Less is known about the characteristics of sperm in short abstinence periods. Hence, the current study was conducted to determine the influence of consecutive ejaculate on above parameters after short abstinence period in oligospermic males.

methodsThis observational study was conducted from January 2018 to February 2019 and included 67 men undergoing primary infertility treatment at the SDM Fertility Centre, Dharwad, India. The first semen sample was provided after an abstinence period of 2-7 days, while the second sample was collected 1-3 h after the first. The two consecutive semen samples were analyzed according to the 2010 WHO criteria for semen analysis and their parameters were compared. Sperm DNA fragmentation was also measured.

resultsMost of the participants were aged of 31 to 40 years (68.6%). The majority of them had the second sample collected after a 1-hour interval (88%); 10.4% of the subjects had the second sample collected after a 2-hour interval; the remaining 1.4% had the second sample collected after a 3-hour interval. Mean concentration (mill/ml), total motility, and progressive motility (%) were significantly higher in the second sample (p<0.05). The second sample also showed lower DNA fragmentation than the first ejaculate sample.

conclusionsOur study inferred that consecutive semen samples collected 1-3 hours apart might have a role in managing subfertility in oligospermic males. Further research, possibly a randomized clinical trial, is needed to explore this association.
