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.

Abstract

Pathogenesis of Mycoplasma pneumoniae infection is considered to be in part attributed to excessive immune responses. Mycoplasma pneumoniae shows strong cytoadherence to host cells and this cytoadherence is thought to be involved in the progression of pneumonia. However, the interaction between the cytoadherence and the immune responses is not known in detail. In this study, we demonstrated that the induction of pro-inflammatory cytokines in the human monocyte cell line THP-1 is dependent on the property of cytoadherence of M. pneumoniae. A wild-type strain of M. pneumoniae with cytoadherence ability induced pro-inflammatory cytokines such as tumour necrosis factor-α and interleukin-1β (IL-1β). Whereas, heat-killed M. pneumoniae and cytoadherence-deficient mutants of M. pneumoniae caused significantly less production of pro-inflammatory cytokines than the wild-type strain. The wild-type strain induced pro-inflammatory cytokines in an endocytosis-independent manners, but the induction by heat-killed M. pneumoniae and cytoadherence-deficient mutants was dependent on endocytosis. Moreover, the wild-type strain induced caspase-1 production and ATP efflux, promoting the maturation of IL-1β and release of the pro-IL-1β precursor, whereas heat-killed M. pneumoniae and the cytoadherence-deficient mutants failed to induce them. These data suggest that the cytoadherence ability of M. pneumoniae activates immune responses and is involved in the pathogenesis of M. pneumoniae infection.
