Association of blood progesterone levels on trigger day and low oocyte retrieval in cases with polycystic ovary syndrome undergoing in-vitro fertilization: A prospective cohort study.

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
Background: The number of follicles aspirated during intracytoplasmic sperm injection (ICSI)/in vitro fertilization (IVF) treatment does not always match the number of oocytes recovered. Objective: This study aimed to assess the oocyte retrieval rate (ORR) distribution data and investigate the risk factors for low ORR in polycystic ovary syndrome (PCOS) cases undergoing IVF/ICSI. Materials and Methods: This prospective cohort study was conducted on 140 women aged between 18 and 40 yr with PCOS who were referred to Arash hospital in Tehran, Iran for ICSI/IVF treatment from March to November 2024. The ratio of obtained oocytes to follicles ( Results: No significant difference was observed between the low and normal ORR groups for progesterone levels. A statistically significant difference was observed in terms of estradiol/follicle ratio above 17, number of follicles above 17, and number of retrieved eggs between the low and normal ORR groups. Logistic regression analysis showed that serum estradiol/follicle ratio ( Conclusion: Low ORR, which results in fewer embryos and more cycle cancellations, may be caused by low progesterone levels on the trigger day, low estradiol levels/follicles (
