Percutaneous Transthoracic Needle Biopsy May Increase Recurrence in Early-Stage Non-Small Cell Lung Cancer: A Propensity Score-Matched Analysis.
Article in Annals of surgical oncology, 2026. 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
backgroundThis study evaluated the association between percutaneous transthoracic needle biopsy (PTNB) and recurrence in early-stage non-small-cell lung cancer (NSCLC).
methodsA retrospective study was conducted to analyze patients with cT1b-2aN0M0 NSCLC who underwent lobectomy between 2009 and 2021. The exclusion criteria ruled out multiple primary lung cancers and bronchoscopic biopsy. Patients were classified into a PTNB group and a non-biopsy group according to whether they underwent preoperative PTNB. Propensity score-matching was applied, and cumulative incidence of recurrence (CIR) was compared. Fine and Gray competing-risk regression was used to evaluate the association between PTNB and recurrence. Subgroup analyses were conducted according to pathologic stage and the presence of high-risk pathologic features.
resultsOf 2208 eligible patients, 674 (30.5 %) underwent PTNB, and 1534 (69.5 %) did not. After propensity score-matching, each group included 416 patients with balanced baseline characteristics. In the matched cohort, the 5-year CIR was significantly higher in the PTNB group (21.1 %; 95 % confidence interval [CI], 18.0-26.1 %) than in the non-biopsy group (13.7 %; 95 % CI, 10.2-17.3 %; P < 0.001). In multivariate competing-risk regression analysis, PTNB was independently associated with increased recurrence risk in models incorporating clinical variables alone (subdistribution hazard ratio [SHR], 1.892; 95 % CI, 1.407-2.545; P < 0.001) as well as in models incorporating both clinical and pathologic variables (SHR, 1.851; 95 % CI, 1.375-2.493; P < 0.001). Subgroup analyses demonstrated that the association between PTNB and recurrence persisted regardless of pathologic tumor-node-metastasis (pTNM) stage and the presence of high-risk pathologic features.
conclusionPreoperative PTNB was associated with an increased risk of recurrence for patients with early-stage NSCLC.
