Occult Node Detection With Lobectomy Versus Segmentectomy for Stage IA NSCLC.
Article in JTO clinical and research reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Objective: Besides the discussion on parenchymal margin, data on the extent of lymph node (LN) dissection are scarce, especially in segmentectomy. This study aimed to investigate the extent of LN dissection and detection of occult disease in segmentectomy compared with lobar resection. Methods: We performed a single-institution, retrospective analysis for patients who underwent segmentectomy or lobectomy for clinical T1N0M0 (≤3 cm) NSCLC from 2012 to 2022. The extent of LN dissection and the rate of detection of occult LN disease were compared. N1 nodes were further classified as collected as a specimen during the operation (N1 dissection) and the nodes retrieved from lung specimens by pathologists (N1 lung specimen). Results: During the study period, 957 lobectomies and 402 segmentectomies were performed for clinical T1N0M0 NSCLC. The median number of sampled LNs was significantly higher in the lobectomy group (18 versus 12; Conclusions: Segmentectomy was associated with less LN sampling, which translated into lower detection of occult nodal metastasis in N1 LNs. Although standardized pathologic dissection could potentially improve detection, there is likely an inevitable inferiority in LN sampling with segmentectomy.
