1 · What the graph read from it

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.

2 · The registry

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

ABA-1 is a major allergen of nematode parasites of the genus Ascaris which includes the large roundworms of humans and pigs, A. lumbricoides and A. suum, respectively. The allergen was purified from A. suum by immunoaffinity chromatography for immunochemical examination. The IgE antibody repertoire is under MHC control in infected rodents and the IgE-binding epitopes were robust to treatment with heat or periodate, and electroblotting on nitrocellulose. This implies that the IgE epitopes comprise primary peptide sequence or an unusually stable secondary or tertiary structure. The molecular mass of ABA-1 is controversial, but mass spectrometry analysis indicated that there were five components of similar size, with the major species being 14,643.2 +/- 1.4 D. Finally, N-terminal sequence analysis of ABA-1 and TBA-1 (the homologue in the canine nematode infective to humans, Toxocara canis) revealed a high degree of similarity, and we have previous evidence that ABA-1 homologues are widespread amongst ascaridid parasites of humans. ABA-1 and its homologues might, therefore, be important to the immunopathology of many infections with nematode parasites, upon which the genetic constitution of the hosts will also have a bearing.
