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

Several lines of evidence suggest a regulatory role of histamine in circadian rhythms, but little is known about signaling pathways that would be involved in such a putative role. The aim of this study was to examine whether histamine mediates its effects on the circadian system through Hrh1 or Hrh3 receptors. We assessed both diurnal and free-running locomotor activity rhythms of Hrh1-/- and Hrh3-/- mice. We also determined the expression of Per1, Per2 and Bmal1 genes in the suprachiasmatic nuclei, several areas of the cerebral cortex and striatum under symmetric 24 h light-dark cycle at zeitgeber times 14 and 6 by using radioactive in situ hybridization. We found no differences between Hrh1-/- and wild type mice in the length, amplitude and mesor of diurnal and free-running activity rhythms as well as in expression of Per1, Per2 and Bmal1 genes in any of the examined brain structures. The amplitude of free-running activity rhythm of the Hrh3-/- mice was significantly flattened, whereas the expression of the clock genes in Hrh3-/- mice was similar to the wild type animals in all of the assessed brain structures. Therefore, the knockout of Hrh1 receptor had no effects on the circadian rhythm of spontaneous locomotion, and a knockout of Hrh3 receptor caused a substantial reduction of free-running activity rhythm amplitude, but none of these knockout models affected the expression patterns of the core clock genes in any of the studied brain structures.
