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: Endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) is a diagnostic technique for assessing intrathoracic lymph nodes and masses. EBUS-TBNA skill is most commonly acquired through training in interventional pulmonology (IP) or thoracic surgery, but there is no consensus on what constitutes appropriate training. Kingston Health Sciences Centre (KHSC) is a Canadian tertiary care academic institution without a formal IP training program that introduced EBUS in 2014. We seek to describe the attainment of EBUS skill by assessing diagnostic performance and to describe acquisition of skill at this non-IP center. Methods: Retrospective analysis of EBUS-TBNA procedures at KHSC since 2014 was conducted. We reviewed the first 70 EBUS procedures performed by each of 4 pulmonologists without prior EBUS training between 2014 and 2019 (n=280). Collected data included patient characteristics, indication for EBUS, number, size, and sites of sampled lymph nodes, and diagnostic yield based on pathology reports. Descriptive statistics were used to assess performance and skill acquisition. Results: The number of EBUS-TBNA procedures increased from 5.3/month in 2014 to 18.3/month in 2019 and 25.5/month in 2023. In the 1 Conclusions: Non-IP trained pulmonologists were able to safely acquire EBUS-TBNA skill at a Canadian academic tertiary care center with a diagnostic accuracy comparable with those reported in literature, within their first 70 cases.
