Metabolizable energy and apparent total tract digestibility of energy and nutrients differ among samples of sunflower meal and sunflower expellers fed to growing pigs.
Article in Journal of animal science, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
An experiment was conducted to test the hypothesis that there are no differences among samples of sunflower coproducts in apparent total tract digestibility (ATTD) of gross energy (GE), crude protein (CP), and acid hydrolyzed ether extract (AEE), total dietary fiber (TDF), insoluble dietary fiber, soluble dietary fiber (SDF), or in metabolizable energy (ME) regardless of where the ingredient was produced. Six samples of sunflower meal (SFM) were obtained from the United States (two samples), Ukraine (two samples), Hungary, and Italy. A sample of sunflower expellers (SFE) from the United States was also used. A corn-based control diet and 7 diets containing corn and each sample of sunflower coproducts were formulated. Sixty-four barrows (initial weight = 31.5 ± 3.2 kg) were allotted to 8 diets using a randomized complete block design with four blocks of pigs from four different weaning groups. Pigs were housed individually in metabolism crates and feed was provided at three times energy requirement for maintenance. Feces and urine were collected for four days after seven days of adaptation to diets. Results indicated that the ATTD of GE and CP in SFE was less (P < 0.05) than in SFM, but ATTD of AEE in SFE was greater (P < 0.05) compared with SFM. No difference in ME between SFM and SFE was observed. The ATTD of GE and TDF in SFM from Ukraine and Hungary was greater (P < 0.05) than in SFM from the United States or Italy. The ATTD of AEE did not differ among SFM samples with the exception that ATTD of AEE in the U.S. 2 sample was greater (P < 0.05) than in the other samples. The ATTD of SDF was less (P < 0.05) in the U.S. 1 sample and the sample from Italy than in the other samples. The ATTD of TDF was greater in the Ukraine 2 sample of SFM (P < 0.05) than in the two U.S. samples. The ME in the SFM samples from Ukraine and in the SFM from Hungary was greater (P < 0.05) than in the U.S. 1 sample and the SFM from Italy. In conclusion, ATTD of GE and nutrients differed between SFM and SFE, but the ATTD of TDF and the ME in SFM was not different from value for SFE. Among SFM samples, relatively small variations in ATTD of GE, AEE, and CP were observed, but ME and digestibility of TDF varied.
