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

A proinflammatory role for glycogen synthase kinase 3beta (GSK-3beta) has been demonstrated. Here, we addressed its roles on heat-inactivated Staphylococcus aureus-induced microglial inflammation. Heat-inactivated S. aureus induced tumor necrosis factor alpha (TNF-alpha) and nitric oxide (NO) production, at least in part, via a Toll-like receptor 2-regulated pathway. Neutralization of TNF-alpha largely blocked heat-inactivated S. aureus-induced NO. Heat-inactivated S. aureus activated GSK-3beta, and inhibiting GSK-3beta reduced TNF-alpha production as well as inducible NO synthase (iNOS)/NO biosynthesis. While activation of NF-kappaB was essential for heat-inactivated S. aureus-induced TNF-alpha and NO, inhibiting GSK-3beta blocked heat-inactivated S. aureus-induced NF-kappaB p65 nuclear translocation. Additionally, inhibiting GSK-3beta enhanced heat-inactivated S. aureus-induced interleukin-10 (IL-10) production (IL-10 is an anti-inflammatory cytokine which inhibits TNF-alpha production). Neutralization of IL-10 reduced TNF-alpha downregulation caused by GSK-3beta inhibition. These results suggest that GSK-3beta regulates heat-inactivated S. aureus-induced TNF-alpha and NO production in microglia mainly by activating NF-kappaB and probably by inhibiting IL-10.
