Establishment of critical values for AMH screening with PCOS based on restricted cubic spline plots.
Article in Endocrine connections, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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 aim is to develop age-specific anti-Müllerian hormone (AMH) screening criteria for polycystic ovary syndrome (PCOS) to facilitate early detection and diagnosis of the condition and subsequently evaluate the screening criteria. Methods: A retrospective analysis was performed on patient data from Hangzhou Women's Hospital between July 2021 and August 2024. The use of restricted cubic spline analysis helped identify age-related inflection points, which were crucial for segmenting the patient population. Statistical analysis was conducted using SPSS software, and the receiver operating characteristic curve was employed to determine the area under the curve, optimal AMH screening thresholds, sensitivity, specificity, Youden index, correct diagnosis rate, positive predictive value and negative predictive value. The established age-related AMH screening criteria for PCOS were then validated using a separate validation group. The consistency of the PCOS age-related AMH screening test with the 2003 Rotterdam PCOS diagnostic criteria was assessed using the kappa statistic. Results: The derived age-specific AMH screening thresholds for PCOS are as follows: ≥6.93 ng/mL (20-27 years old), ≥5.06 ng/mL (28-30 years old) and ≥4.19 ng/mL (31-39 years old). Conclusion: The age-stratified AMH screening criteria demonstrated high sensitivity, specificity and accuracy in identifying PCOS, indicating a strong predictive value. However, the development of more robust and universally applicable diagnostic criteria for PCOS will require additional multicenter, prospective clinical trials for further validation.
