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

introductionThe aim of the study was to examine the protective efficacy of astaxanthin (ASTA) against the damage that occurs during sperm cryopreservation.

methodsThis experimental study was carried out on waste semen samples of 30 normozoospermic individuals who applied for semen analysis. Semen samples were divided into four equal volumes and 0 μM (control group), 50 μM, 100 μM, and 500 μM ASTA were added to each group. All groups were stored frozen in a liquid nitrogen tank. Semen samples were removed from liquid nitrogen after 72 hours and were thawed. Motility evaluation of sperm was performed. In addition, sperm was stained with acidic aniline blue to detect DNA chromatin condensation.

resultsThe highest motility loss was found in the control group and the least motility loss was in the 100 μM ASTA group. When examined in terms of sperm chromatin condensation, condensed sperm count was higher in the 100 μM ASTA group than in the other groups.

conclusionsIt has been observed that ASTA added to the cryoprotectant substance during sperm cryopreservation positively affects sperm motility and reduces the number of decondensed sperm.
