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

Diseases associated with Chlamydia infection, such as pelvic inflammatory disease and ectopic pregnancy, are due to inflammation-mediated tissue damage and scarring that occur after chronic or repeated infections. The inflammatory chemokine interleukin-8 (IL-8) is produced by Chlamydia-infected cells through an endogenous mechanism of activation, independent of soluble factors in the supernatant. The host signaling pathways necessary for this response are not understood, but the mitogen-activated protein kinase (MAPK) extracellular signal-regulated kinase (ERK) has been shown to be activated at similar times as IL-8 mRNA up-regulation. The purpose of this study was to elucidate the MAPK pathways necessary to induce the endogenous IL-8 response to Chlamydia trachomatis infection of epithelial cells. IL-8 induced by infection with C. trachomatis L2 was shown to be dependent on ERK and independent of p38 and Jun N-terminal MAPK by use of chemical inhibitors of the signaling pathways. Persistent ERK activation during IL-8 mRNA production at 24 h postinfection was necessary to maintain the response. C. trachomatis serovar D also induced IL-8 in an ERK-dependent manner. We concluded that IL-8 induced during infection of epithelial cells is dependent on continual activation of ERK by C. trachomatis.
