Cloning, expression and antioxidant activity of a novel collagen from Pelodiscus sinensis.
Article in World journal of microbiology & biotechnology, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Collagen is the main structural protein of various connective tissues in animals and naturally plays an important role within the body. It is increasingly used within certain areas, such as medicine, citology and cosmetology. The soft-shelled turtle (Pelodiscus sinensis) is a commercially important aquatic species rich in collagen. In this study, a novel collagen gene fragment of 756 bp, which encodes 252 deduced amino acid residues, including 25 conserved Gly-X-Y motifs, was cloned from a soft-shelled turtle. Recombinant soft-shelled turtle collagen (rSTC) was stably expressed in Escherichia coli Rosetta and purified by His GraviTrap affinity columns. The antioxidant activities of rSTC were measured using hydroxyl and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals. The results showed that rSTC quenched the free radicals in a dose-dependent manner. The hydroxyl radical scavenging activity (HRSA) of rSTC was 98.9 % at a concentration of 3 mg/mL. At a concentration of 5 mg/mL, rSTC exhibited a DPPH radical scavenging activity of 32.7 %. At the tested concentrations, rSTC exhibited higher HRSA and lower DPPH radical scavenging activity.
