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
In this study, sea buckthorn oil (SBO) was added to rainbow trout fish diets at 0.25%, 0.5%, and 1% rates in order to determine the effects on growth, feed conversion rate, survival rate, fillet quality, and physiological, biochemical and histopathological parameters. The experiment was designed in four groups with three replicates each including 20 fish with 18 ± 3 g and lasted for 45 days. Fish were fed three times a day and weighed biweekly. At the end of the experiment, significant differences were determined with respect to specific growth rates (SGR), weight gains (WG), and feed conversion ratios (FCR) (P < 0.05), except for survival ratios (SR) (P > 0.05). Sea buckthorn oil improved fish fillet quality and weight gain rates by up to 27% compared to control. The pepsin, amylase, lipase, and trypsin enzyme activities differed significantly (P < 0.05) from those of the control group. Serum lysozyme myeloperoxidase (MPO) and plasma nitro blue tetrazolium (NBT) levels differed significantly (P < 0.05) in the 0.5% and 1% groups compared to the control group, except for the 0.25% group. Liver catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPx), and malondialdehyde (MDA) levels significantly differed in all groups, especially in the 0.5% and 1% groups compared to the control group (P < 0.05). SBO supplementation to feed caused significant changes in the FA profiles, especially 18:00 in ∑SFA; 16:1 in ∑MUFA; 20:5n-3 and 20:2n-6 in ΣPUFA; 20:5n-3 in ∑n-3; and 20:2n-6 in ∑n-6 in rainbow trout (P < 0.05). There were no histopathological changes between the control and the experimental groups. The determined data suggested that 1% SBO may be successfully used as a feed additive in rainbow trout.
