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

The membrane lipoproteins of Treponema pallidum and Borrelia burgdorferi have potent immunostimulatory properties in vitro, implicating them as major inflammatory mediators in syphilis and Lyme disease. Recently, we reported that synthetic lipohexapeptide analogs (lipopeptides) of the lipoproteins could be used as surrogates for native spirochetal lipoproteins in immune cell activation studies in vitro. The present study was designed to evaluate the inflammatory properties of the lipopeptides in vivo and to correlate the cellular responses to these synthetic analogs with the histopathology of syphilis and Lyme disease. Lipopeptides corresponding to the 47-kDa major membrane lipoprotein of T. pallidum and the outer surface protein A of B. burgdorferi injected intradermally induced dose-dependent dermal inflammation in mice; the initial predominantly neutrophilic (mice) or heterophilic (rabbits) cellular infiltrates were followed by infiltrates consisting predominantly of mononuclear cells. The intradermal response of rabbits to the 47-kDa lipopeptide was strikingly similar to that observed for animals infected intradermally with T. pallidum. In all cases, lipopolysaccharide was substantially more potent as an inflammatory mediator than the spirochetal lipopeptides. In contrast to the lipopeptides, nonacylated hexapeptides elicited minimal or no dermal lesions in mice or rabbits, underscoring the importance of acyl modification to the inflammatory properties of the lipopeptides. This study provides the first in vivo evidence that the spirochetal lipoproteins/lipopeptides contribute to the immunopathogenesis of syphilis and Lyme disease.
