Isolation, characterization, and biomedical potential of phycoerythrin phycobiliprotein from Kappaphycus alvarezii (Doty) L. M. Liao: antimicrobial, antioxidant, and anticancer activities.
Article in Scientific reports, 2025. 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
Kappaphycus alvarezii (Doty) L. M. Liao, a red seaweed widely cultivated for carrageenan polysaccharide, is also a potential source of the valuable pigment phycoerythrin (PE). Therefore, this study aims to extract phycoerythrin from K. alvarezii, evaluate its antimicrobial, antioxidant, and anticancer activities, and identify its biomedical potential for future therapeutic applications. The protein content of phycoerythrin pigment extracted from K. alvarezii was found to be 69.84% and showed excellent antimicrobial activity against Klebsiella oxytoca and Proteus mirabilis, with a minimum inhibition zone of 11 mm. It showed significant in vitro antioxidant activity, as analyzed using total antioxidant, hydrogen peroxide scavenging, reducing power, DPPH, and ABTS assays. Further, the pigment exhibited potent cytotoxicity against a human lung cancer cell line, with an IC
