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

Chronic heart failure (CHF) is characterized by increased sympathetic tone. The glutamatergic input in the rostral ventrolateral medulla (RVLM), which is a key region involved in sympathetic outflow, seems not to be involved in the generation of sympathetic tone in the normal state. The aim of this study was to determine the role of the RVLM glutamate receptors in the generation of sympathetic tone in CHF. CHF was produced by coronary artery ligation. Bilateral microinjection of the glutamate receptor antagonist kynurenic acid, the N-methyl-d-aspartate (NMDA) receptor antagonist D-2-amino-5-phosphonopentanoate, or the non-NMDA receptor antagonist 6-cyano-7-nitroquinoxaline-2,3-dione into the RVLM dose-dependently reduced resting blood pressure and renal sympathetic nerve activity in CHF but not in sham rats. Picoinjection of kynurenic acid (100 pmol in 5 nL) significantly decreased the basal discharge by 47% in 25 RVLM presympathetic neurons in CHF rats. In contrast, kynurenic acid had no effect on the discharge in all 22 of the RVLM presympathetic neurons tested in sham rats. These data suggest that upregulated glutamate receptors, including NMDA and non-NMDA, in the RVLM are involved in tonic control of elevated sympathetic tone in CHF.
