Level of in vitro storage of the European catfish (Silurus glanis L.) eggs at different temperatures.

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
European catfish (Silurus glanis) is a commercially important freshwater fish originating from Eastern Europe. The objective of this study was to examine the short-term storage of its eggs especially in relation to maintaining a low level of malformation in newly hatched fry. The eggs from freshly spawned individuals were stored separately in cell incubators at 17 and 22 °C under aerobic conditions. Changes in fertilization, hatching, and malformation were examined in eggs stored at 1, 3, 5, and 7 h post-stripping. The sperm used for fertilization showed very good motility rates (84-90%) and curvilinear velocity (110-125 μm/s), and straight-line velocity did not drop below 77 μm/s. For all females, a temperature of 17 °C was better than 22 °C for egg storage in vitro. Egg fertilization and total hatching decreased rapidly after 7 h storage at 17 °C. The storage time of eggs in vitro to fertilization should therefore not exceed 5 h at 17 °C. In all females, there was no difference in the total number of eggs hatching between 1 and 3 h of egg storage at 17 °C. The storage time of eggs did not correlate with the level of malformations of the fry. However, the level of hatching and malformations was clearly affected by the storage temperature of eggs when it was > 17 °C. Analysis showed that the storage time of eggs, temperature of storage, and individual females had a significant influence on fertilization and total hatching rates. Regression analysis confirmed a low correlation of fertilization and hatching rates with storage time of eggs.
