The costo-uterine muscle of the rat. Fluorescence-histochemical and electron microscope studies during growth, pregnancy and oestrogen-treatment.

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.
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
The costo-uterine muscle provides a skeletal attachment to the longitudinal myometrial layer of the uterine horn. In this study we investigated the possibility that the muscle is responsive to sex steroid hormones. In rats of 4 weeks of age, injected with oestradiol for 5 days, the cross-sectional area of nucleated muscle cell profiles was significantly increased. A significant increase in the sectional area of muscle cells was also demonstrated in the costo-uterine muscle of 16-week-old rats, on the 20th day of gestation, compared with non-pregnant rats in dioestrus and of the same age. In oestrogen-treated and in pregnant rats, there was also an increase in muscle cell length. As to the innervation of the costo-uterine muscle, in glyoxylic acid-treated whole-mount and cryostat preparations, we found not only perivascular nerve fibres, but also a few nerve fibres innervating the muscle proper. The pattern of innervation was unchanged after oestrogen treatment and during pregnancy. In the electron microscope, axonal varicosities were observed in the proximity of both vascular and non-vascular muscle cells.
