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: Progesterone levels are critical for endometrial receptivity and implantation success in assisted reproductive technology (ART). The purpose of the current study was to determine whether serum progesterone levels on oocyte retrieval day predict pregnancy success in fresh embryo transfers. Methods: This cross-sectional study was conducted at a university-affiliated infertility clinic in Tehran, Iran, in 2024. Blood samples were collected to analyze serum levels of estradiol (E2), progesterone (P4), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and anti-Müllerian hormone (AMH) using standardized methods. Student's t-test and the Mann-Whitney U test and Logistic regression were applied for statistical analyses participants. The optimal progesterone cutoff was calculated by receiver operating characteristic (ROC) curve with level of statistical significance of 0.05. Results: The mean age of participants was 35.56±4.45 years and their mean BMI was 25.98±2.2. Among those who underwent fresh embryo transfer (n=63), 21 had positive serum β-hCG results, and fetal heart rate was detected via ultrasound in 17 patients at six weeks. Progesterone levels were significantly higher in the pregnancy-confirmed group (8.46 Conclusion: Elevated serum progesterone levels on the day of oocyte retrieval may predict positive pregnancy outcomes, highlighting the importance of monitoring progesterone to optimize the success rate of ART.
