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
This study was conducted to systematically evaluate the regulatory effects of kaempferol (KAE) on lipid metabolism, immune function, inflammatory responses, and antioxidant capacity in late laying hens. A total of 288 49-week-old Jinghong No. 1 laying hens with uniform body weight and consistent laying performance were randomly assigned to four treatment groups, with six replicates per group and 12 hens per replicate. Following a 1-week acclimation period, a formal feeding trial was conducted for 10 weeks. The control group (CON) was fed a basal corn-soybean meal diet, while Experimental Groups I, II, and III received the same basal diet supplemented with 0.2, 0.4, and 0.6 g/kg KAE, respectively. In terms of lipid metabolism, compared with the CON group, dietary KAE supplementation in Groups I, II, and III significantly reduced hepatic vacuole area, with the most pronounced effect observed in Group II; additionally, Groups II and III had significantly lower serum triglyceride (TG) levels and egg yolk total cholesterol content (
