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
introductionPositron emission tomography/CT (PET/CT) may have an important role in guiding decisions regarding biopsy of high-risk lung nodules suspicious for lung cancer. The PET-FIRST study aimed to assess the role of PET/CT prior to any biopsy of a high-risk lung nodule.
methodsA prospective study was performed in two tertiary hospitals. A study multidisciplinary team (MDT) was established (independent of the hospital Tumour Board) to review referrals of lung nodules with an intermediate-high (≥10%) risk of malignancy by Brock score. A two-stage consensus assessment was undertaken by the MDT regarding choice of biopsy: (1) based on the referral CT alone and then (2) after unblinding the results of PET/CT. The primary study outcome was change in biopsy decision.
results168 patients were included in the study; of these, 53% of nodules were malignant, 44% were benign and 3% cases refused follow-up. In 59 of the 168 patients (35%), the initial recommended biopsy decision was changed based on PET/CT findings. Regarding whether to biopsy the nodule or not, in 42 cases (25%), the initial management decision was changed after PET/CT (p<0.01). Sensitivity analysis showed that the benefit of having PET/CT before nodule biopsy was observed across all ranges of Brock scores. There was an estimated total cost reduction by procedure avoidance of $AA60 796 ($AA362 per patient).
conclusionsIn patients with lung nodules of intermediate-high risk for lung cancer, fluorodeoxyglucose PET/CT performed prior to any biopsy of the nodule has a significant effect in determining biopsy choice.
