Risk prediction of multiple-station N2 metastasis in patients with upfront surgery for clinical single-station N2 non-small cell lung cancer.
Article in Scientific reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
To investigate long-term outcomes and develop a risk model for pathological multi-station N2 (pN2b) in patients who underwent upfront surgery for clinical single-station N2 (cN2a) non-small cell lung cancer (NSCLC). From 2006 to 2018, 547 patients who had upfront surgery for suspected cN2a NSCLC underwent analysis. A risk model for predicting pN2b metastasis was developed using preoperative clinical variables via multivariable logistic analysis. Among 547 clinical cN2a NSCLC patients, 118 (21.6%), 58 (10.6%), and 371 (67.8%) had pN0, pN1, and pN2. Among 371 pN2 NSCLC patients, 77 (20.8%), 165 (44.5%), and 129 (34.7%) had pN2a1, pN2a2, and pN2b. The 5-year overall survival rates for pN2a1 and pN2a2 were significantly higher than for pN2b (p = 0.041). Histologic type (p < 0.001), age ≤ 50 years (p < 0.001), preoperatively confirmed N2 metastasis (p < 0.001), and clinical stage IIIB (vs. IIIA) (p = 0.003) were independent risk factors for pN2b metastasis. The risk scoring system based on this model demonstrated good discriminant ability for pN2b disease (area under receiver operating characteristic: 0.779). In cN2a NSCLC patients, those with multiple N2 metastases indicate worse prognosis than those with a single N2 metastasis. Our risk scoring system effectively predicts pN2b in these patients.
