Comparing Complications Between Shape-Sensing Robotic-Assisted Bronchoscopy and Trans-Thoracic Needle Pulmonary Biopsy Approaches: Insights From a Large Nationally Representative Administrative Database.
Article in Thoracic cancer, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundShape-sensing robotic-assisted bronchoscopy (ssRAB) is a navigation platform for biopsy of indeterminate pulmonary lesions. Large-scale, real-world evidence confirming the safety profile of ssRAB compared to transthoracic needle biopsy (TTNB) is needed. STUDY DESIGN AND
methodsA retrospective cohort study was performed using the PINC AI healthcare database among patients who underwent ssRAB or TTNB lung lesion biopsy at participating hospitals between April 2019 and March 2023. Outcomes were rates of pneumothorax and pneumothorax requiring chest-tube intervention within 3 days, and rates of in-hospital bleeding or all-cause death. Quasi-binomial logistic regression analysis was performed after one-to-five propensity score matching (PSM) accounting for patient- and hospital-related characteristics.
resultsA total of 119 424 patients (5121 ssRAB, 114 303 TTNB) were identified with 4554 ssRAB and 14 319 TTNB patients after PSM. Relative to ssRAB, TTNB had significantly higher risk of pneumothorax (18.4% vs. 2.6%, OR = 7.10, p < 0.001) and pneumothorax requiring chest-tube (10.8% vs. 1.4%, OR = 7.62, p < 0.001). TTNB was associated with a higher risk for bleeding (1.5% vs. 0.6%, OR = 2.20, p < 0.001) and all-cause death (0.48% vs. 0.15%, OR = 2.47, p = 0.023); however, rates for both outcomes were relatively low.
interpretationIn this large-scale, real-world database analysis with diverse patient populations, physician experience, and health care settings, ssRAB demonstrated a better safety profile compared to TTNB. Superior safety combined with a potentially comparable performance profile and known advantages of bronchoscopy, including concurrent staging, support ssRAB as an optimal choice for non-surgical biopsies for suspicious pulmonary lesions.
