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
Background: Lung cancer has a high recurrence rate after successful surgical treatment. This study deals with possible risk factors and recommendations to improve the treatment of non-small cell lung cancer (NSCLC). Methods: In this retrospective analysis, we used data of all NSCLC patients who underwent lobectomy at the Lung Cancer Center Munich between 2011 and 2020. Only patients with postoperative T1-4, N0, R0, M0 were included. We compared numerical outcomes between patients with distant, lymph node, local recurrence and no recurrence using analysis of variance (ANOVA), and categorical outcomes using Chi-squared test or Fisher's exact test when cell numbers were <6. We used logistic regression models to identify factors significantly associated with the occurrence of a distant, lymph node and local recurrence. Results: Tumor size in cm was significantly higher in patients with local recurrence (mean 5.5) followed by distant recurrence (mean 4.0), lymph node recurrence (mean 3.1) and patients with no recurrence (mean 3.0), p<0.0001. Diffusing capacity for carbon monoxide (DLCO) in % was significantly higher in patients with no recurrence (72.9) and decreased with distant recurrence (67.0), local recurrence (66.7) and lymph node recurrence (65.8), p=0.01. There were no significant differences in postoperative complications, surgical approach or number of lymph node assessed. A tumor size ≥4.65 cm was identified as an independent marker for local recurrence. Conclusion: For patients with NSCLC ≥4.65 cm, which corresponds to UICC stage IIA and higher, multimodal therapy should be discussed. The surgical approach has no influence on recurrence.
