Comparison of Superovulated Embryo Quality in Simmental Cattle Inseminated with 0 °C-Refrigerated and Liquid Nitrogen-Frozen Semen.

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
Semen quality plays a crucial role in bovine in vivo embryo production. This study aimed to compare the effects of 0 °C-refrigerated semen and liquid nitrogen-frozen semen on embryo quality in Simmental cattle. Semen collected from five bulls was equally divided into two groups: one diluted with a 0 °C refrigeration solution and stored at 0 °C, and the other diluted with a cryopreservation solution and stored in liquid nitrogen for 24 h. We evaluated sperm motility, progressive motility (assessed via a computer-assisted sperm analyzer), acrosome integrity, and plasma membrane integrity in both groups. Fifty superovulated Simmental cows were artificially inseminated with semen from both groups. Embryos were non-surgically flushed on day seven, followed by BrdU proliferation staining and TUNEL apoptosis staining. Proliferation and apoptosis levels were quantified using marker genes. Results showed that 0 °C-refrigerated semen exhibited significantly higher sperm motility, progressive motility, acrosome integrity, and plasma membrane integrity compared to liquid nitrogen-frozen semen (
