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

Metabolic profile and leptin presence and expression of receptor in the ovary of 8 queens were analyzed. All queens were assessed for nutritional state and underwent ovariectomy in accordance with Italian law for the control of stray cats and dogs. Three queens were at early gestation, three prepubescent and two non-pregnant. All animals appeared healthy but underweight. Haemogram and biochemical profile did not show to be of prognostic value. On microscopy, granulosa cells of secondary follicles tested positive to leptin in pregnant queens, while testing negative in non-pregnant ones. Muscular layer of vessels of the ovary in non-pregnant queens tested positive to receptor, but negative in those found pregnant. Results suggest that leptin is produced and receptor expressed in the different tissues of the ovary in underweight queens. Additionally, the expression of receptor did not necessarily imply local leptin production and clearly displayed to vary according to the reproduction phase. Taken altogether, these findings allow to conclude that the expression of receptor can be interpreted as the pillar bridging ovary tissues as target sites of circulating leptin produced elsewhere. Arguably, ovary removal may affect hormonal cross-talk at the systemic level, likely affecting different systemic functions, including the nutritional status.
