Comparative studies on the immunogenicity of theronts, tomonts and trophonts of Cryptocaryon irritans in grouper.
Article in Parasitology research, 2008. 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
Cryptocaryon irritans is a ciliated obligate parasite of marine fish, causing white spot disease in tropical and sub-tropical regions. Recent studies have shown that fish can mount immune responses against C. irritans and acquire protection. The present study compared the protective immunity in grouper (Epinephelus coioides) against C. irritans induced by theronts, trophonts and tomonts via intraperitoneal (i.p.) injection and tentatively identified an immobilization antigen. Specific antibody titres of immunized fish serum were determined by enzyme-linked immunosorbent assay and immobilization assays at weeks 0, 1, 2, 4, 6 and 8 post-immunization, and immunized grouper were challenged with theronts to detect the survival percentage of fish. Fish immunized with theronts produced higher levels of serum antibody against C. irritans than fish immunized with trophonts or tomonts. A significantly higher level of immune protection was achieved in fish immunized with theronts but not in fish immunized with tomonts or trophonts. Western blot analysis using polyclonal immobilization antibodies of rabbit immunized with theront revealed an immunoreactive band of the protective (immobilization) antigens of C. irritans, the size of which is approximately 34 kDa. The sera of mice immunized with the protein could immobilize theronts of C. irritans. These results demonstrated that the theront stage of C. irritans elicited stronger protective immunity than the trophont and tomont stages in grouper. The tentative identification of protective antigen provides the solid foundation for the development of a defined vaccine against C. irritans.
