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

Previous studies have shown that chlamydial infection is accompanied by significant infiltration of neutrophils at the site of infection. However, the role of neutrophils in host defence against chlamydial infection is not clearly understood. Using genetically different inbred mouse strains and CXCR-2 gene knockout (KO) mice, we examined the mechanism for neutrophil recruitment and the role of neutrophils during chlamydial lung infection. Our data showed that C3H mice exhibited significantly higher and more persistent neutrophil infiltration in the lung than did C57BL/6 mice following Chlamydia trachomatis mouse pneumonitis infection. The massive neutrophil infiltration in C3H mice was paralleled by high-level expression of CXCR-2 and its ligands, CXC chemokines (macrophage inflammatory protein 2, cytokine-induced neutrophil attractant (KC) and lipopolysaccharide-induced CXC chemokine), and proinflammatory cytokines (tumour necrosis factor-alpha, interleukin-1 and interleukin-6) in the lung. Although much greater infiltration of neutrophils was observed in C3H mice than in C57BL/6 mice, the former mice had more severe disease and higher in vivo chlamydial growth than the latter. Moreover, CXCR-2 KO mice, which revealed a dramatic reduction in neutrophil activity, showed comparable chlamydial infection to wild-type mice. These results suggest that neutrophils are not efficient for controlling chlamydial lung infection.
