Effect of uterine torsion intrapartum on concentrations of placental estrogens and progesterone in cattle.
Article in Veterinary medicine and science, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectiveThe current study investigates how uterine torsion influences placental oestrogens and progesterone blood concentrations in intrapartum cows. Our research tests the hypothesis that intrapartum uterine torsion impairs the ability of the placenta to synthesize steroids and may also suppress the release of synthesized steroids into the maternal circulation.
methodsThe study included a total number of 37 intrapartum dairy cows of various breeds and ages. These animals were transported to our clinic by their owners. Furthermore, general and obstetrical examinations of all these animals were performed in our clinic. The uterine torsion (UT) group consisted of 20 animals. The presence of UT was verified during clinical general examinations by vaginal and transrectal examination. The comparison (C) group included 17 animals whose birth was undisturbed or could be terminated with moderate obstetrical assistance. The clinical examination of group C animals showed no problems with their general health and genital organs. Blood samples were collected immediately after the initial obstetrical examination from 37 cows for radioimmunological measurement of estradiol-17β (E2), free total estrogen (FTE), conjugated total estrogen (CTE), and progesterone (P4).
resultsIn terms of P4, there was no statistical difference between the two groups. For all estrogen parameters, however, concentrations were significantly lower in the UT group than in the C group. In the correlation analysis, there was a significant correlation between the P4 and the FTE in the C group. Furthermore, the positive correlation between all estrogen parameters in the UT group was significant. In group C, significant positive correlations were found apart from the correlation between E2 and CTE.
conclusionsThe results are consistent with the hypothesis and suggest that in UT animals processes dependent on estrogens or other placental hormones may be impaired during the peri- or postpartum period.
