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

Surface molecules of parasitic stages of the nematode Nippostrongylus brasiliensis can be readily iodinated by the chloramine T technique, and assessed for antigenic reactivity with humoral antibody from infected animals. Free-living infective larvae are less amenable to analysis by this, or similar methods, but within 18 hr of larvae entering the host, new macromolecular surface antigens can be detected. The parasites change their surface antigens twice more in the course of the maturation to the adult stage. Surface antigens are stage-specific: lung larvae (L3), intestinal larvae (L4) and gut-living adults each possess characteristic sets of cuticular molecules. Single stage infections result in antibody reactive only to the antigens from the homologous stage. The adult surface appears to bear the greatest number of antigens, one of which is found only on the male worm. The composition of these antigens does not differ grossly between adult worms from a naive or immune host, or worms established after the adaptation of a 'trickle' (multiple low dose) infection. There appears to be an interesting contrast between the rapidity and extent of changes in surface antigens in the early phases of infection, and the stability of adult antigens analysed at different points in the host immune response.
