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

Equine conceptus development is a critical study area due to its significant implications for the equine breeding industry. Following a high fertilization success rate of 71-96 % (Ball, 1988), it is concerning that 30-40 % of developing embryos may not survive beyond the crucial initial two weeks of gestation, coinciding with the onset of gastrulation (Ball, 1988). The pregnancy in mares lasts 330-345 days. The underlying molecular mechanisms of the embryonic period are not fully explained in mares. During early pregnancy in mares, the following takes place: the descent of the blastocyst from the oviduct to the uterus around 5-6 days post-fertilization; migration of the spherical conceptus, surrounded by a glycoprotein capsule in the uterine lumen; fixation of the vesicle near the base of the uterine horn around 16-17 days post-fertilization; implantation; development of endometrial cups that produce chorionic gonadotropin, as well as an additional corpus luteum that produces progesterone. In mares, there is no clear determination of what constitutes the early signal of pregnancy recognition. The results of previous research indicate that mechanical stimuli,
