Effects of different doses of silk peptide on energy metabolism during exercise in mice
Article in Journal of exercise nutrition & biochemistry, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
purposeThis study was carried out to determine the optimal dose of silk peptide for enhancing fat metabolism during exercise.
methodsFifty male ICR mice were randomly divided into five groups: Sed, SP0, SP200, SP400, and SP800. All SP mice underwent training by running on a treadmill 5 times a week for 2 weeks (20 m/min, 8° slope, 50 min/day for the first week and 25 m/min, 8° slope, 50 min/day at about 70-75% of maximum oxygen uptake for the second week).
resultsAfter the 2 weeks, fat oxidation was measured during a 1-h exercise at the training conditions of the second week and was found to be 1.02 ± 0.15, 1.04 ± 0.17, 0.98 ± 0.10, 1.14 ± 0.19, and 1.15 ± 0.07 g/kg/h for Sed, SP0, SP200, SP400, and SP800 groups, respectively. The SP800 group had significantly higher fat oxidation levels than the SP0 group did at 36, 40, and 56 min and the Sed group did at 2, 4, 6, 8, 12, 14, 16, 20, 40, 46, 50, 52, 56, and 60 min. However, there was no significant difference among the groups in carbohydrate oxidation during the 1-h exercise. SP doses of 200 mg/kg and 400 mg/kg did not show any effect on fat and carbohydrate oxidation.
conclusionIn conclusion, 800 mg/kg of silk peptide is the optimal dose for enhancing fat metabolism during exercise. In addition, silk peptide treatment could reduce body weight by enhancing fat metabolism.
