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: Chronic obstructive pulmonary disease (COPD) is associated with frequent complications after transthoracic biopsy. Radial probe endobronchial ultrasound-guided transbronchial lung biopsy (RP-EBUS-TBLB) is widely used to diagnose peripheral pulmonary lesions (PPLs). However, the efficacy and safety of this procedure for the diagnosis of PPLs in patients with COPD remain poorly understood. We investigated the usefulness of RP-EBUS-TBLB for diagnosing PPLs in patients with COPD. Methods: This retrospective observational study aimed to identify clinical outcomes of RP-EBUS-TBLB in patients with COPD. A total of 175 patients with COPD and 439 patients without COPD were included in this study. RP-EBUS-TBLB was performed without fluoroscopy using a guide sheath. Results: The overall diagnostic accuracies in patients with COPD and without COPD were 80.6% (141/175) and 78.8% (346/439), respectively. There was no significant difference in the diagnostic yield based on the severity of airflow limitation (80.0%, 81.4%, and 79.2% for mild, moderate, and severe to very airflow limitations, respectively; P=0.97). In patients with COPD, diagnostic yields for malignant and benign lesions were 85.6% (95/111) and 71.9% (46/64). In multivariable analyses, larger lesion size [≥30 mm; odds ratio (OR), 2.86; 95% confidence interval (CI): 1.10-7.45; P=0.03] and within the lesion on EBUS image (OR 9.29; 95% CI: 3.79-22.79; P<0.001) were associated with diagnostic success in patients with COPD, whereas lesion location of upper lobe (OR, 0.36; 95% CI: 0.14-0.92; P=0.03) were associated with diagnostic failure. The overall complication rate in our study was 7.4% (13/175) in patients with COPD. Pneumothorax occurred in 4.6% (8/175), and chest tube insertion was needed in 1.7% (3/175) of the patients. Conclusions: RP-EBUS-TBLB can be used as an appropriate method to diagnose PPLs in patients with COPD. The size of the lesion (≥30 mm) and having the probe within the lesion were important for successful diagnosis. The location of the lesion in the upper lobe is associated with diagnostic failure. No difference was observed in the diagnostic yield based on the severity of airflow limitation. The complication rates were acceptable.
