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

Periodic ovulation in rats, mice and hamsters is the result of a surge in luteinising hormone (LH) that depends on circadian gating signals emerging from the master circadian clock within the suprachiasmatic nucleus (SCN) and rising ovarian oestrogen levels. These two signals converge into the anteroventral periventricular nucleus (AVPV) and lead to the release of kisspeptin, which is responsible for surges of gonadotrophin-releasing hormone and, in turn, of LH release. How the AVPV integrates circadian and reproductive signals remains unclear. In the present study, we show that the female rat AVPV itself shows circadian oscillations in the expression of the clock genes PER1 and BMAL1, which lie at the core circadian clockwork of mammals. In ovariectomised females treated with oestradiol (E₂), these oscillations are in synchrony with the AVPV rhythmic expression of the KISS1 gene and the gene that codes for the arginine-vasopressin (AVP) receptor AVPr1a. Although clock gene oscillations are independent of oestrogen levels, circadian expression of Kiss1 and Avpr1a (also referred to as V1a) mRNA is blunted and absent, respectively, in ovariectomised animals without E₂ replacement. Because AVP is considered to be a critical SCN transmitter to gate the LH surge, our data suggest that there is a circadian oscillator located in the AVPV, and that such a putative oscillator could, in an oestrogen-dependent manner, time the sensitivity to circadian signals emerging from the SCN and the release of kisspeptin.
