PET-CT in mediastinal staging of non-small cell lung cancer: analysis of false results.
Article in Polish journal of radiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 analyse the risk and factors associated with false-negative (FN) and false-positive (FP) positron emission tomography-computed tomography (PET-CT) results in the mediastinal staging of non-small cell lung cancer. Material and methods: This retrospective cohort study analysed data from a prospective database. It included patients with lung cancer who underwent preoperative staging with PET-CT, endobronchial ultrasound, and endoscopic ultrasound, followed by curative-intent anatomical lung resection with systematic lymph node dissection. Statistical analyses were performed to identify factors associated with FN and FP PET-CT results. Results: Data from 781 patients were analysed. FN results were significantly associated with more advanced PET-CT-based stages and CT-based stage IIB. FP results were significantly associated with male sex, adenocarcinoma histology, CT-based disease stage, and SUV Conclusions: False-negative PET-CT results in the diagnosis of mediastinal lymph node involvement were more likely to occur in PET-CT-based stages IB and IIB and less likely to occur in stage IIIA. FP results were more likely to be expected in men, with higher SUV
