Minimally invasive segmentectomy and lobectomy for peripheral stage IA1-2 non-small-cell lung cancer: a case-matched cohort study from a UK Centre.
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. Cited by 4 papers.
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 objective of this study is to compare in a real-world series the short- and long-term results of segmentectomy and lobectomy for peripheral clinical stage IA non-small-cell lung cancer (NSCLC).
methodsSingle-centre cohort study including a series of consecutive patients undergoing minimally invasive segmentectomy or lobectomy for peripheral (outer third of the lung) clinical stage IA NSCLC (January 2017-August 2022). Propensity score case matching analysis generated 2 matched groups of patients undergoing segmentectomy or lobectomy. Short-term (morbidity and mortality) and long-term [overall survival and event-free survival (EFS)] outcomes were compared between the 2 matched groups. EFS was calculated by including death resulting from any cause and any recurrence as events.
resultsPropensity score generated 118 pairs of patients undergoing minimally invasive segmentectomy or lobectomy. The median follow-up was 30 months (95% confidence limits (CL) 4-64). The median postoperative length of stay was 4 days in both groups. Ninety-day mortality was similar (segmentectomy 2.5% versus lobectomy 1.7%, P = 1). Three-year overall survival [segmentectomy 87% (76-93) versus lobectomy 81% (72-88), P = 0.73] and EFS [segmentectomy 82% (72-90) versus lobectomy 78% (68-84), P = 0.52] did not differ between the groups. Loco-regional recurrence rate [segmentectomy 4.2% (5/118) versus lobectomy 9.3% (11/118), P = 0.19] was similar despite a lower nodal upstaging [segmentectomy 3.4% (4/118) versus lobectomy 14% (17/118), P = 0.005]. The occurrence of compromised resection margins (pR1 or pR uncertain) was similar between the groups [segmentectomy 7.6% (9/118) versus lobectomy 9.3% (11/118), P = 0.81].
conclusionsThis observational series confirms the non-inferiority of segmentectomy compared to lobectomy in treating peripherally located stage IA NSCLC.
