Pathologic upstaging and survival outcomes for patients undergoing segmentectomy versus lobectomy in clinical stage T1cN0M0 non-small cell lung cancer.
Article in JTCVS open, 2025. 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
Objectives: To assess the impact of the extent of surgical resection on overall survival in patients with clinical T1cN0M0 (cT1cN0M0) non-small cell lung cancer (NSCLC), with and without pathologic nodal upstaging (pN1+). Methods: The National Cancer Database (NCDB) was queried to identify patients with cT1cN0M0 NSCLC who underwent lobectomy or segmentectomy without receiving neoadjuvant therapy between 2010 and 2021. Bivariate analyses were performed to compare demographic and clinical characteristics across surgical groups. Propensity score matching was used to compare outcomes of segmentectomy versus lobectomy. Cox proportional hazard models and Kaplan-Meier survival estimates were used to assess the association of overall survival on the interaction between extent of resection and pathologic nodal upstaging. Results: A total of 22,945 patients were analyzed, including 21,875 (95.3%) who underwent lobectomy and 1070 (4.7%) who underwent segmentectomy. Pathologic nodal upstaging to pN1+ occurred in 14.5% of lobectomy cases and in 6.6% of segmentectomy cases. Propensity score-matched analysis revealed that patients undergoing segmentectomy had comparable overall survival to those undergoing lobectomy (hazard ratio [HR], 1.00; 95% confidence interval [CI], 0.86-1.16), and those undergoing segmentectomy with pN1+ had comparable overall survival to those undergoing lobectomy with pN1+ (HR, 1.04; 95% CI, 0.65-1.66). Conclusions: In patients with cT1cN0M0 NSCLC, overall survival outcomes are similar between segmentectomy recipients and lobectomy recipients, including those incidentally found to have pN1+, suggesting a potential role of lobe-preserving approaches. Additionally, completion lobectomy may not offer a survival benefit in cT1cN0M0 patients incidentally discovered to have pathologic N1 nodes.
