The effects of methionine administration during the beginning postnatal days on the ovarian structures in adult rats.
Article in Veterinary medicine and science, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectivesMethionine is known as an essential amino acid in mammals. Consuming excessive amounts of methionine has toxic effects. This study aimed at evaluating the histomorphometric and histopathologic changes of ovaries after methionine administration during follicle formation. MATERIAL AND
methodsA total of 60 newborn female rats born under similar conditions were selected and randomly assigned into three groups including control, recipients of 50 and 200 mg/kg body weight of methionine for 5 days. On day 120, all 60 female rats were euthanized and the whole left ovary of each animal was taken in order to count the number of primordial, primary, secondary, antral, atretic follicles, as well as corpora lutea and also to conduct histopathologic study.
resultsAccording to the results, the 50 mg/kg methionine did not significantly change the number of primordial follicles compared to the control group but the 200 mg/kg dose significantly decreased the number of primordial follicles. There were no significant differences between the groups in the number of other types of follicles and also in the number of corpora lutea. There was no histopathological lesion in the groups.
conclusionsIt seems that the high dose of methionine could exacerbate apoptosis of the primordial ovarian follicle during the follicle assembly process. However, the remaining were enough to form later stages of follicles after puberty.
