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

objectiveTo study whether follicular growth and oocyte maturation can be improved by antimüllerian hormone (AMH) modulation at specific stages of follicular development.

designPrimary and secondary follicles were cultured in a matrix-free system and were assigned to the control group and the group with AMH supplementation during the preantral stage and neutralizing AMH antibody addition during the antral stage.

settingNational primate research center. ANIMAL(S): Adult, female rhesus macaques (Macaca mulatta). INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Follicle survival, growth, steroid and paracrine factor production, and oocyte competence were evaluated. Follicles were assessed for expression of genes that are critical for gonadotropin signaling, cumulus cell glycolysis, and oocyte quality. RESULT(S): Primary follicles formed "organoids" and developed to the antral stage in group culture. AMH exposure during the preantral stage increased organoid diameters. Oocytes from the AMH-treated organoids had greater diameters and matured to the metaphase II (MII) stage. Secondary follicles developed to the antral stage during individual culture. The AMH exposure during the preantral stage and AMH antibody treatment during the antral stage increased follicle diameters, vascular endothelial growth factor and follistatin production, differentiation factor 9 expression, and oocyte diameters. The MII oocytes from the AMH-modulated group developed to the morula stage after IVF, with one to the blastocyst stage. CONCLUSION(S): AMH supplementation at the preantral stage and depletion at the antral stage enhanced primate follicular development and oocyte competence in vitro. The improved embryonic development supports in vitro follicle maturation as a potential approach for fertility preservation.
