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
Several studies have indicated that feeding female animal with fatty acids could result in alteration of offspring sex ratio; however, there is little information available regarding the effect of feeding male animal with fatty acids on sex ratio of offspring. The aim of current study was to investigate the effect of paternal feeding with n-3 and n-6 polyunsaturated fatty acids (PUFAs) on sperm characteristics and sex ratio of offspring in mice. Male mice received 2.50% of palm oil (control), fish oil (n-3 PUFAs) or sunflower oil (n-6 PUFAs) for two months. Sperm kinematics and viability were assessed using computer-assisted sperm analyzer and eosin-Y staining, respectively. Additionally, female mice were randomly introduced to males of three experimental groups to determine reproductive parameters including litter size, conception rate and sex ratio. Fish oil enhanced sperm concentration, motility and viability, whereas sunflower oil decreased sperm concentration. Nevertheless, progressive motility, velocity, linearity and straightness of sperms were not affected by source of fatty acids. Although supplementation with fish oil resulted in male-biased sex ratio, palm and sunflower oils did not impact sex ratio. Besides, source of fatty acids failed to influence conception rate and litter size. In conclusion, the present study provided evidence for the impact of paternal fish oil consumption on sex ratio of offspring for the first time. Moreover, it showed beneficial effect of n-3 PUFAs and adverse effects of n-6 PUFAs on seminal parameters.
