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

Connective tissues are the most common area of colonization for the Lyme disease spirochaete Borrelia burgdorferi. Colonization is aided by the interaction between numerous bacterial adhesins with components of the extracellular matrix (ECM). Here we describe a novel interaction between B. burgdorferi and the major ECM proteoglycan found in joints, aggrecan. Using affinity chromatography and mass spectrometry we identify two borrelial aggrecan-binding proteins: the known ECM ligand Bgp (BB0588) and an uncharacterized protease BbHtrA (BB0104). Proteinase K studies demonstrate that BbHtrA is surface exposed. Immunoblots using sera from patients with both early and late Lyme disease establish that BbHtrA is expressed during human disease, immunogenic, and conserved in the three major Lyme disease spirochaete species. Consequences of the interaction between aggrecan and BbHtrA were examined by proteolysis assays. BbHtrA cleaves aggrecan at a site known to destroy aggrecan function and which has been previously observed in the synovial fluid of patients with Lyme arthritis. These data demonstrate that B. burgdorferi possess aggrecan-binding proteins which may provide the organism with additional capability to colonize connective tissues. Moreover, our studies provide the first evidence that B. burgdorferi possess proteolytic activity which may contribute to the pathogenesis of Lyme arthritis.
