Effect of the use of vitamin "E" in the diluent on the viability of ram sperm.
Article in Tropical animal health and production, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The sperm membrane is damaged in cryopreservation processes; this damage can be minimized using antioxidants such as vitamin E. The objective of the present study was to evaluate the effect of the addition of vitamin "E" on the viability of ram sperm during preservation processes. Two experiments were carried out; in the first, 32 ejaculates were used, which after evaluation were divided into two aliquots for processing; the first received Triladyl + vitamin "E" (T + E), and the second received only Triladyl (T); these aliquots were cooled and stored at 5 °C for 24 h. The viability (sperm motility, integrity, and membrane permeability) was evaluated at 0 and 24 h after dilution. In the second experiment, the same procedure was performed as experiment 1, except that the samples were also frozen, and the viability was evaluated at zero and 48 h post-freezing. Dependent variables were analyzed using mixed models in a split plot design. In experiment 1, the integrity and permeability of the sperm membrane was better in the group: "T + E" (P <0.05). In experiment 2, the vitamin significantly improved (P <0.05) the sperm viability. It is concluded that the addition of vitamin "E" improves sperm viability.
