The role of 18F-fluorodeoxyglucose positron emission tomography/computed tomography SUVMax in deciding on a computed tomography-guided lung biopsy in solid solitary pulmonary nodules.

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
objectiveThe aim of this study was to calculate a useful cut-off point of the 18F-fluorodeoxyglucose positron emission tomography/computed tomography SUVMax value to decide on a computed tomography-guided percutaneous transthoracic needle biopsy for solitary pulmonary nodules of sizes between 11 and 20 mm.
methodsBetween January 2015 and April 2020, patients with solitary pulmonary nodules who underwent computed tomography-guided percutaneous transthoracic needle biopsy were retrospectively reviewed, and those with solitary pulmonary nodules of 11-20 mm in diameter, who had undergone an 18F-fluorodeoxyglucose positron emission tomography/computed tomography examination before computed tomography-guided percutaneous transthoracic needle biopsy, were included in the study. A total of 76 patients who met the inclusion criteria were evaluated.
resultsThere was no distinguishing finding on the computed tomography examination (p>0.05). The SUVMax values of the malignant solid solitary pulmonary nodules were higher than the benign solitary pulmonary nodules (p<0.05).
conclusionThe benign and malignant solid solitary pulmonary nodules between 11 and 20 mm have similar computed tomography features. 18F-fluorodeoxyglucose positron emission tomography/computed tomography is a useful imaging technique for distinguishing benign and malignant solitary pulmonary nodules. Notably, 4.85 SUVMax value can be used to decide on a computed tomography-guided percutaneous transthoracic needle biopsy procedure in solid solitary pulmonary nodules between 11 and 20 mm with excellent sensitivity and moderate specificity rates.
