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
Background: This study aims to evaluate the clinical value and safety of hand-drawn mapping for bronchoscopic navigation combined with radial probe endobronchial ultrasound (RP-EBUS) in the diagnosis of primary peripheral sputum smear-negative pulmonary tuberculosis (SNPTB). Methods: Patients suspected of having peripheral-type primary SNPTB, who were admitted to Southeast University Zhongda Hospital from 2021 to 2024, were retrospectively analyzed. Patients were divided into two groups. The sensitivity, specificity, diagnostic accuracy rate, and area under the receiver-operating characteristic (ROC) curve were evaluated with different diagnostic methods. Results: A total of 212 patients were enrolled, including 149 in the SNPTB group and 63 in the non-SNPTB group. The success rate of ultrasound bronchoscopy exploration is 90.6 %. The sensitivity, specificity, diagnostic accuracy, and AUC value of bronchoscopy guided by hand-drawn mapping were 92.6 %, 95.2 %, 93.4 %, and 0.939, respectively, which were superior to those of T-SPOT detection ( Conclusions: For peripheral SNPTB, the combination of hand-drawn navigation and RP-EBUS is both safe and effective. EBUS-BALF mNGS demonstrated the highest diagnostic efficiency. When radial ultrasound detects hypoechoic areas of the lesion, it is recommended to perform BALF mNGS. Conversely, in solid lesions, the negative rate of BALF mNGS is relatively high, and combining mNGS with biopsy is recommended to further improve diagnostic efficiency.
