Dietary Vitamin E Is More Effective than Omega-3 and Omega-6 Fatty Acid for Improving The Kinematic Characteristics of Rat Sperm.
Article in Cell journal. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
objectiveAlthough key roles for dietary vitamin E (VITE) and fatty acid (FA) in fertility have been confirmed, limited data are available on the effects of VITE alone, or a constant level of VITE supplemented by dietary omega-6 and omega-3 FAs in combination on male reproduction. Consequently in this paper, the effects of VITE, sunflower oil, fish oil and their combination on rat sperm were investigated. MATERIALS AND
methodsWe divided 50 mature male Wistar rats into 5 groups (n=10) in a experimental completely randomized design for eight weeks: i. Control (CTR): standard diet; ii. Vitamin E diet (VITE): 2 times greater than recommendations; iii. Sunflower oil group (n-6) [gavaged with 0.5 ml/day/rat sunflower oil+VITE diet]; iv. Fish oil group (n-3): [gavaged with 0.5 ml/day/rat fish oil+VITE diet] and v. n-3+n-6 group [gavaged with 0.3 ml fish oil/day/rat+0.2 ml sunflower oil/day/rat+VITE diet]. The sperm parameters were measured by computer assisted semen analyzer (CASA). All data were analyzed with SPSS software.
resultsFeed intake decreased in groups which were administered sunflower oil compared with the other groups (P<0.05). The groups which received only VITE or fish oil+VITE had a significantly higher concentration of sperm compared with the n-6+n-3 and CTR group (P<0.05). VITE and n-3 showed significant improved progressive motility compared to the CTR group, whereas the n-6 and n-6+n-3 groups were in the middle (P<0.05). The highest sperm kinematic parameters were observed in the VITE only group. There was no strong correlation between sperm parameters and blood lipid profiles.
conclusionDietary VITE and fish oil+VITE can improve sperm quality. Our findings can be a focus for improvements in sperm quantity and motility in fertile animals using only dietary VITE.
