Stimulation of Ovulation in Immature Female Rats Using Orthosteric and Allosteric Luteinizing Hormone Receptor Agonists.
Article in Doklady. Biochemistry and biophysics, 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
Human chorionic gonadotropin (hCG) and luteinizing hormone (LH) are widely used for the treatment of reproductive disorders and for controlled ovulation induction, but their use is limited by side effects. Allosteric agonists of the LH/hCG receptor, including thieno[2,3-d]thienopyrimidine TP03 developed by us, can become an alternative. TP03 (50 mg/rat, i.p.) when administered to immature female rats treated 48 h before with Follimag has been shown to increase progesterone levels (maximum 8 h post-treatment) and induce ovulation, as indicated by the appearance at 24 h corpus luteum (8.6 ± 0.5 per ovary). In terms of its activity, TP03 is comparable to hCG, although it acts more moderately. In the ovaries, unlike hCG, TP03 does not lead to an increase in the expression of vascular endothelial growth factor, which can cause ovarian hyperstimulation syndrome. Thus, TP03 is a promising drug as an ovulation inducer and ovarian steroidogenesis stimulator.
