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

Sperm cryopreservation and assisted reproduction are powerful tools for the conservation of endangered species. The domestic cat has been a useful model for studying wild felid reproductive biology due to the limited availability of endangered individuals for experimental research. Here, we investigate the effect of cryodiluents (TEST vs. Biladyl) and the timing of glycerol addition (before vs. after refrigeration, in one vs. three steps, respectively) on post-thaw sperm quality (motility, acrosome integrity) and their subsequent in vitro fertilization (IVF) ability with homologous oocytes. The results showed no statistically significant differences in sperm traits when samples were cryopreserved in TEST or Biladyl, or when glycerol was added in one or three steps. Motile sperm and intact acrosomes were significantly correlated before and after cryopreservation, indicating consistent relationships in fresh and thawed samples. The use of Biladyl significantly reduced IVF rates after cryopreservation compared to fresh sperm. Cryopreservation in TEST led to IVF rates that were not significantly different from those of fresh sperm. Using swim-up after thawing, or adding 1 mM pentoxifylline, did not enhance IVF results. Overall, a TEST cryodiluent with 4% glycerol added in one step is a reliable option for preserving epididymal cat spermatozoa.
