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

Mycobacterium leprae, the causative agent of leprosy, is an obligate intracellular pathogen. M. leprae can infect a variety of cells in vivo, including epithelial cells, muscle cells, and Schwann cells, in addition to macrophages. The ligand-receptor interactions important in the attachment and ingestion of M. leprae by these nonmacrophage cells remains unknown. Fibronectin (FN) significantly enhances both attachment and ingestion of M. leprae by epithelial and Schwann cell lines. We cloned an M. leprae FN binding protein (FN attachment protein [FAP]) distinct from the 85ABC complex which has been shown previously to bind FN. The FAP open reading frame predicts a protein of 29.5 kDa with a 39-amino-acid signal peptide and was previously described as an antigen in leprosy patients. M. leprae FAP has homologies in M. vaccae, M. avium, and M. tuberculosis, as determined by Southern blotting and direct peptide analysis. Both anti-FAP antibodies and an Escherichia coli-expressed recombinant protein significantly blocked M. leprae attachment and internalization by T-24, an epithelial cell line, and JS1, a Schwann cell line. These data suggest that FN can be a bridging opsonic ligand for attachment of mycobacteria to nonphagocytes and that FAP plays an important role in this process. This may be an important step in the initiation of M. leprae infection in vivo.
