Computed Tomography-Guided Percutaneous Core Needle Biopsy of Lung Lesions:
Article in Sultan Qaboos University medical journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Objectives: This study aimed to evaluate the diagnostic yield and complications associated with computed tomography (CT)-guided transthoracic core-needle biopsy (CNB) of lung lesions and to identify factors influencing biopsy outcomes. Methods: This retrospective study included patients who underwent CT-guided CNB of lung lesions at Sultan Qaboos Comprehensive Cancer Care & Research Centre, University Medical City, Muscat, Oman, from November 2021 to December 2024. Patients were categorised as either having undiagnosed lung masses/nodules or suspected pulmonary metastases from known malignancies. Biopsies were performed using an 18-gauge coaxial needle, following standard protocols. Diagnostic yield, sample adequacy for molecular analysis and complications were analysed using descriptive statistics and Chi-squared or Fisher's exact tests Results: A total of 105 patients were included. Diagnostic yield of CT-guided CNB was 81.9% (n = 86) with malignancy confirmed in 72.4% of cases. Diagnostic yield significantly correlated with lesion size with increasing accuracy for lesions >2.1 cm compared to those <1 cm (93.9% versus 55%; Conclusion: CT-guided lung biopsy demonstrated high diagnostic yield with acceptable rates of complications. Lesion depth and size had significant impacts on diagnostic success and occurrence of complications. These results support that CT-guided CNB is a safe and reliable diagnostic procedure for lung lesions, especially when lung lesions are superficially located and solid.
