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 association of Chlamydia pneumoniae and atherosclerosis has been well documented. Recently, it has been demonstrated that C. pneumoniae up-regulates expression of the lectin-like ox-LDL receptor (LOX-1) in endothelial cells. Many of the pro-atherogenic effects of ox-LDL occur through its activation and uptake by LOX-1. This class E scavenger receptor contains a carbohydrate-recognition domain common to the C type lectin family. Previously, we have demonstrated that the major outer membrane protein of the chlamydiae is glycosylated and glycan removal abrogates infectivity of C. pneumoniae for endothelial cells. In this study, we investigated whether C. pneumoniae binds to LOX-1. The results show that 1) infection of endothelial cells by C. pneumoniae is inhibited by ligands that bind to the LOX-1 receptor, but not by ligands binding to other scavenger receptors; 2) anti-LOX-1 antibody inhibits C. pneumoniae infectivity, while antibodies against other scavenger receptors do not; 3) anti-LOX-1 antibody inhibits attachment of C. pneumoniae to endothelial cells; and 4) C. pneumoniae co-localizes with LOX-1. These effects were not observed for Chlamydia trachomatis. In conclusion, C. pneumoniae binds to the LOX-1 receptor, which is known to promote atherosclerosis.
