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
purposeTo develop a noble on-site dual screening system for sperm concentration and hyaluronidase (HAdase) activity of male fertility based on lateral-flow assay methods, and to evaluate the effectiveness of this dual screening system. MATERIALS AND
methodsA chromogenic reaction for sperm count was established using a sperm-specific antibody against sperm antigen-10 (SP-10). Substrate-enzyme reaction was developed in which the activity of sperm HAdase on hyaluronic acid (HA) substrates could be measured through a color reaction. The colored HA substrates were degraded and the color faded by the sperm HAdase. To evaluate the validity of the developed methods, the results were compared using 49 semen samples (normozoospermia, 20; oligozoospermia, 9; azoospermia, 20) whose sperm counts were confirmed by the conventional method.
resultsUsing color reaction by SP-10, no signal was observed in azoospermia and low count of sperm (<16×10⁶/mL), and the color signal increased as the count of sperm increased in normal and high count of sperm (≥16×10⁶/mL). The assay system for sperm HAdase activity was successfully developed. In the HAdase assay, the stronger the enzyme activity, the lower the color signal. Through statistical analysis, it was confirmed that there was a statistically significant correlation between sperm count and HAdase activity.
conclusionsIt was successfully developed that a novel on-site dual screening system for sperm count and HAdase activity, simultaneously. We are expecting that this novel dual assay system will provide the accessible and useful information about male fertility at on-site or home.
