1 · What the graph read from it

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.

2 · The registry

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 and Objectives: Despite the emergence of advanced ancillary technologies, the transbronchial method to peripheral pulmonary lesions (PPLs) remains a challenge for bronchoscopists. The objective of the study is to assess the diagnostic value and safety of a novel thin Convex Probe Endobronchial Ultrasound (TCP-EBUS) scope in transbronchial needle aspiration (TBNA) for PPLs suspicious of malignancy. Methods: This single-center feasibility study prospectively enrolled patients with PPLs between August 2022 and January 2023. All lesions were biopsied by EBUS-TBNA using the novel TCP-EBUS scope (BF-UC290F, Olympus) and the prototype 22G aspiration needle (Vizishot2 22G, Olympus). The primary end point was the diagnostic yield. Results: Thirty-three subjects were evaluated, and 30 subjects were included in the final analysis. The mean patients' age was 62.4 ± 10.2 years, and 60% were male. The mean lesion size was 25.7 ± 6.8 mm, and 22 nodules were ≤30 mm. PPLs were situated adjacent to the subsegmental or sub-subsegmental bronchi (25 and 5, respectively), and the EBUS scope was advanced into segmental or subsegmental bronchi (12 and 18, respectively). Average number of punctures was 3.8 ± 1.3. Adequate specimens were obtained in all 30 (100%) of the cases. The overall diagnostic yield was 90% (27/30). No serious adverse events were observed. Conclusions: The TCP-EBUS has decent accessibility to more distal intrapulmonary lesions. TCP-EBUS-TBNA is a safe real-time procedure with a high sensitivity for malignant PPLs in the inner two-thirds of the lung, irrespective of the presence of a bronchus sign.
