Lobe-Specific Risk of Malignancy in Parotid Gland Lesions: A Milan System-Based Analysis.

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
Purpose: To evaluate the diagnostic accuracy of fine-needle aspiration cytology (FNAC) for parotid gland lesions using the Milan System while eliminating verification bias, and to systematically compare risk of malignancy (ROM) between superficial and deep lobe lesions across all Milan categories. Methods: A retrospective review was conducted of 332 patients who underwent ultrasound-guided FNAC and subsequent surgical excision between 2019 and 2025. Cytology results were classified according to the Milan System. ROM values and diagnostic performance metrics were calculated for each category, with subgroup analysis according to lobe location. Final pathology results were available for all cases, ensuring complete diagnostic verification. Results: Histopathology confirmed malignancy in 37 cases (11.1%), with significantly higher frequency in the deep lobe compared to the superficial lobe (24.6% vs. 7.9%, Conclusion: FNAC with Milan System classification provides reliable diagnostic performance for parotid lesions. However, anatomical location significantly influences malignancy risk, with deep lobe lesions carrying substantially higher ROM across multiple diagnostic categories. Level of Evidence: 3.
