Results of video-assisted thoracoscopic surgery versus thoracotomy for lung cancer in a mixed practice medium-volume hospital: a propensity-matched study.
Article in Interdisciplinary cardiovascular and thoracic surgery, 2023. 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
objectivesThe aim of this study was to compare the short- and long-term results of video-assisted thoracoscopic surgery (VATS) and thoracotomy for non-small-cell lung cancer in a medium-volume centre, where cardiothoracic surgeons perform both cardiac and general thoracic surgery. The primary outcome of interest was 5-year overall survival and disease-specific survival. Secondary outcomes were short-term postoperative complications, length of hospital stay and lymph node yield.
methodsThis was a retrospective cohort study including 670 lung cancer patients undergoing VATS (n = 207) or open surgery (n = 463) with a curative intent in Oulu University Hospital between the years 2000-2020. Propensity score matching was implemented with surgical technique as the dependent and age, sex, Charlson comorbidity index, pulmonary function, pathological stage, histological type and the year of the operation as covariates resulting in 127 pairs.
resultsIn the propensity-matched cohort, 5-year overall survival was 64.3% after VATS and 63.2% after thoracotomy (P = 0.969). Five-year disease-specific survival was 71.6% vs 76.2% (P = 0.559). There were no differences in overall (34.6% vs 44.9%, p = 0.096) or major postoperative complications (8.7% vs 14.2%, P = 0.167) between the study groups. The average length of hospital stay was shorter (5.8 vs 6.6 days, P = 0.012) and the median lymph node yield was lower (4.0 vs 7.0, P < 0.001) in the VATS group compared to the thoracotomy group.
conclusionsAccording to this study, the long-term results of lung cancer surgery in a mixed practice are comparable between VATS and open surgery.
