Ovarian-Adnexal Imaging-Reporting and Data System (O-RADS) ultrasound version 2019: a prospective validation and comparison to updated version (v2022) in pathologically confirmed adnexal masses.
Article in European radiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
objectiveTo evaluate the diagnostic accuracy and reliability of the Ovarian-Adnexal Reporting and Data System (O-RADS) ultrasound v2019 in classifying adnexal masses (AMs) and compare the old and updated systems (v2022). PATIENTS AND
methodsThis prospective study enrolled 977 consecutive women with suspected AMs from three institutions between January 2022 and December 2023. Ultrasound examinations were performed by three experienced radiologists who categorized AMs according to O-RADS ultrasound v2019. The same radiologists retrospectively reviewed the stored ultrasound images and provided the O-RADS ultrasound v2022 classification. Histopathology was used as the reference standard to calculate the diagnostic accuracy of the O-RADS versions in predicting malignant AMs. Inter-observer agreement (IOA) of the O-RADS scoring results was evaluated using the Fleiss kappa (κ) test.
resultsThe final analysis included 803 women with 855 AMs (219 (25.6%) malignant and 636 (74.4%) benign). Both O-RADS versions demonstrated good diagnostic accuracy, with area under the curve (AUC) values ranging from 0.906 to 0.923 (v2019) and 0.919 to 0.936 (v2022). The updated v2022 showed a slightly higher accuracy (82.5-86.7% vs. 80.7-85.3%), sensitivity (93.6-95.0% vs. 92.2-94.1%), and specificity (78.1-84.1% vs. 76.1-82.9%) compared to v2019. The IOA for the overall O-RADS classification was perfect for both versions (κ = 0.96-0.97).
conclusionsThe O-RADS ultrasound classification system demonstrated good diagnostic accuracy and reliability in predicting malignant AMs, with the updated v2022 showing modest improvements. KEY POINTS: Question Accurate classification of adnexal masses is essential for management. Can updated O-RADS ultrasound v2022 improve diagnostic accuracy and reliability compared to v2019 in predicting malignancies? Findings O-RADS ultrasound v2022 demonstrated slightly higher diagnostic accuracy for identifying malignant adnexal masses compared to v2019, reflecting modest improvements in risk stratification and clinical decision-making. Clinical relevance The updated O-RADS ultrasound v2022 provides improved risk stratification for adnexal masses, enhancing diagnostic confidence, supporting more precise clinical decision-making, and improving patient outcomes through timely intervention or tailored management strategies in ovarian cancer care.
