Specific IgG4 response directed against the 45-kDa glycoprotein in trichinellosis: a re-evaluation of patients 15 years after infection.
Article in European journal of clinical microbiology & infectious diseases : official publication of the European Society of Clinical Microbiology, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
The aim of this study was to evaluate the humoral immune response in late human trichinellosis with particular attention to the presence of IgG4 antibodies directed against the Trichinella-45-kDa glycoprotein (gp). This study re-evaluates subjects 15 years after they were involved in a trichinellosis outbreak that occurred in Central Italy following the consumption of raw boar meat infected with Trichinella britovi. The results show that ELISA tests using the E/S antigen identified five IgM- and eight IgG-positive patients and no IgA-positive patients. Tests using immunoblot (IB) with E/S antigens identified three IgM-, five IgA-, seven- IgG1- and three IgG4-positive sera. When the purified 45-kDa gp was used as an antigen, the IB revealed that six of the ten sera tested were positive for IgG4. Sera were also evaluated with a commercial kit, revealing that 11 of 12 patients had a highly sensitive reactivity against Trichinella proteins (64 and 44-43 kDa). In conclusion, humoral immune response against Trichinella is still present in these patients 15 years after the initial infection, including an IgG4 response directed to the 45-kDa gp.
