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
Delayed or failed postpartum estrus can impede the reproductive performance of rebreeding dams. Our study aimed to test whether dietary fish oil can promote estrus return and improve fecal microbiota in multiparous sows. Forty-five sows were randomly allocated into three treatments: a basal diet, or a basal diet plus 30 or 60 g/day of fish oil from gestation day 90 to lactation day 21. Results showed that dietary fish oil significantly elevated circulating DHA in sows, without significant changes in litter size, litter weight, or backfat loss. Supplementation of fish oil (30 or 60 g/day) shortened the interval from weaning to estrus by 1.8 days and 1.67 days, respectively, associated with a significant boost of estradiol. Increases in prolactin and IgA were only significant in the high-dosage group. In addition, plasma MDA and antioxidant activities were up-regulated by fish oil, combined with elevated serum IL-1β and IL-6. Moreover, dietary fish oil significantly reduced serum zonulin, improved the Simpson index of fecal microbiota, and increased the abundance of
