Purification and biochemical characterization of a superoxide dismutase from the soluble fraction of the cyanobacterium, Spirulina platensis.
Article in World journal of microbiology & biotechnology, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
A superoxide dismutase (SOD) was purified from Spirulina platensis sonicate. The SOD was purified to homogeneity (48-fold and 0.24% yield) through ammonium sulphate precipitation and DEAE-52 anion exchange chromatography. The SOD from S. platensis appeared to be a homodimer with a molecular weight of 30 kDa and a subunit MW of 15 kDa as determined by both native polyacrylamide gel electrophoresis and mass spectrometry. The enzyme activity was stable at pH 6.5-10.0 and 50 °C. Using group-specific chemical modifying reagents, the amino acids arginine, histidine, tryptophan, tyrosine and aspartic acid were identified to be essential for S. platensis SOD activity. The amino acid composition was found to lack methionine and cysteine. The inhibition of activity by H2O2 suggests that the enzyme may be an iron containing SOD.
