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

To determine whether the p44/p42 MAPK (ERK1/2) signaling pathway is involved in the activation of CRH-containing neurons in the hypothalamic paraventricular nucleus (PVN) after bacterial lipopolysaccharide (LPS) administration, Sprague Dawley rats were injected with LPS, and studied after 2, 6, 9, and 12 h. In saline-treated controls, isolated weak phosphorylated (phospho)ERK1/2 immunoreactive neurons were observed in the PVN. However, a dramatic increase in phospho-ERK1/2 immunoreactivity was apparent in the PVN 2 h after LPS administration, and gradually declined to baseline levels 9-12 h after injection. By double-labeling immunofluorescence, all CRH-containing neurons in the PVN contained phospho-ERK1/2 2 h after LPS. Intracerebroventricular administration of the MAPK inhibitor, PD98059, prevented LPS-induced ERK1/2 phosphorylation, c-fos activation, and the increase of CRH gene expression in the PVN but had no effect on c-fos activation in brainstem A2-C1/C2 regions. We conclude that LPS rapidly increases the phospho-ERK1/2 in CRH-containing neurons in the PVN and that activation of MAPKs is necessary for LPS-induced activation of the hypothalamic-pituitary-adrenal axis.
