National trends, variation and short-term outcomes in surgery for non-small cell lung cancer in England, 2015-2023: a population-based cohort study using linked national cancer registration and hospital administrative data.
Article in BMJ open, 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
objectivesTo evaluate temporal changes in surgical practice, centre-level variation and short-term postoperative outcomes among patients undergoing lung resection for non-small cell lung cancer (NSCLC) in England between 2015 and 2023.
designPopulation-based cohort study using linked national cancer registration and Hospital Episode Statistics data.
settingSecondary care in England, including all specialist thoracic surgical centres.
participantsAdults (≥18 years) diagnosed with NSCLC in England between 1 January 2015 and 31 December 2023. Patients with linked Hospital Episode Statistics records were included and those undergoing lung resection comprised the surgical cohort. OUTCOME MEASURES: Annual resection rates, procedure type, operative approach, centre-level variation in segmentectomy use and robotic-assisted thoracoscopic surgery (RATS) adoption, 90-day mortality, 30-day emergency readmission and postoperative length of stay. Multivariable regression models adjusted for patient and clinical case mix.
resultsAmong 308 117 patients with NSCLC, 54 138 (17.6%) underwent lung resection. The resection rate increased from 15.4% in 2015 to 20.9% in 2023, while the proportion of patients diagnosed with stage I disease increased from 17.4% to 26.8%. Segmentectomy use increased from 11.2% to 20.6%, pneumonectomy declined fourfold and minimally invasive surgery increased from 47.1% to 79.7%. In 2023, centre-level variation was marked in segmentectomy for small stage IA tumours (risk-adjusted range 10.7%-80.3%) and RATS use (range 0%-67%). 90-day mortality decreased from 4.03% to 2.26%, length of stay shortened and readmission remained stable at approximately 10%-12%. Each successive year of diagnosis was associated with lower 90-day mortality after adjustment for case mix (adjusted OR 0.95, 95% CI 0.93 to 0.98).
conclusionsBetween 2015 and 2023, surgical management of NSCLC in England changed substantially, with increased resection rates, greater use of segmentectomy and minimally invasive approaches and improved short-term postoperative outcomes. However, persistent variation in segmentectomy use and robotic adoption suggests that implementation of contemporary surgical practice remains heterogeneous across centres.
