Diagnosis of unexposed tumours using endobronchial ultrasonography with a guide sheath and a thin transbronchial needle.

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
Transbronchial diagnosis of unexposed lung tumours is challenging in clinical practice. Although modified transbronchial needle aspiration (TBNA) is used for this purpose, the diagnostic yield is unsatisfactory. In such cases, conventional endobronchial ultrasonography with a guide sheath and transbronchial biopsy (TBB) is also ineffective. We found TBB was feasible by placing a guide sheath with a thin transbronchial needle into the tumours. We report two cases of unexposed tumours diagnosed successfully with this technique. Case 1 presents a typical carcinoid in the peripheral lung. Case 2 presents a squamous cell carcinoma at the third bifurcation of the right lung. TBB samples obtained this way were larger than TBNA samples. Moreover, multiple TBBs were possible once the guide sheath was inserted intratumourally. In the modern era of precision medicine, larger amounts of tissues are required for multiple downstream analyses. This novel technique will make a significant contribution towards diagnosing unexposed lung tumours.
