Anisakis haemoglobin is a main antigen inducing strong and prolonged immunoreactions in rats.

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
Anisakis simplex larvae are well known to cause gastrointestinal and allergic manifestations after ingestion of parasitized raw or undercooked seafood. The antibody recognition dynamics against the components of Anisakis larval antigen after primary and re-infection with Anisakis live larvae remain unclear. For this study, immunoblot analyses of serum IgG, IgE, and IgM against Anisakis larval somatic extract were performed in rats that had been orally inoculated with A. simplex live larvae. Multiple antigen fractions were recognized after primary infection. Their reaction was enhanced after re-infection. Antibody recognition was observed for 12 weeks after re-infection. The fraction of approximately 35 kDa contained a main antigen that induced strong and prolonged immunoreactions in IgG and IgE. The antibody reaction to this fraction appeared to be enhanced after inoculation of larval homogenates. This fraction was heat tolerant with boiling for 30 min. The fraction was spotted by immunoblotting after two-dimensional electrophoresis and was identified as Anisakis haemoglobin (Ani s 13) using mass spectrometry analysis. The amino acid sequences of haemoglobin mRNAs from two A. simplex sensu stricto and one Anisakis pegreffii were identified by RACE-PCR. They differed from those of two isolates of Pseudoterranova decipiens and A. pegreffii. Results of this study show that Anisakis haemoglobin, which is known to be a major allergen of A. simplex, induces strong and prolonged immunoreaction in rats. This report is the first to show the amino acid sequence variation of Anisakis haemoglobin mRNA between A. simplex sensu stricto and A. pegreffii.
