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

Enteropathogenic Escherichia coli (EPEC) strains are a common cause of infantile diarrhea in developing countries. EPEC strains induce a characteristic attaching and effacing (A/E) lesion on epithelial cells. A/E lesion formation requires intimin, an outer membrane adhesin protein. The cell-binding activity of intimin is localized at the C-terminal 280 amino acids of the polypeptide (Int280). So far, four distinct Int280 types (alpha, beta, gamma, and delta) have been identified. The aim of this study was to identify immunodominant regions within the Int280alpha and Int280beta domains. Recombinant DNA was used to construct and express overlapping polypeptides spanning these domains. Rabbit anti-Int280 antisera and human colostral immunoglobulin A were reacted with these polypeptides in Western blots and enzyme-linked immunosorbent assays. The results obtained with the rabbit antisera showed the presence of two separate immunodominant regions which are common to both Int280alpha and Int280beta. The first localized within the N-terminal region of Int280, and the second localized between amino acids 80 and 130. The results with the human colostra revealed one reactivity pattern against the Int280alpha fragments but two different reactivity patterns against the Int280beta domain.
