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
Patients with non-small cell lung cancer (NSCLC) and incomplete resection have poor clinical outcomes. The present study aimed to identify risk factors for disease progression and mortality. A total of 65 patients with early-stage NSCLC that underwent operation but had a non-R0 resection between August 2011 and December 2020 were included in the present study, and the clinicopathological features and driver gene mutation status were analyzed. The median follow-up time was 36.2 months; 39 patients (60.0%) experienced disease progression and 3 patients (4.6%) died. In total, 22 patients (33.8%) harbored mutations in driver genes. Multivariate analysis demonstrated that the presence of driver gene mutations was associated with an increased risk of disease progression [adjusted odds ratio, 24.08; 95% confidence interval (CI), 2.77-209.01; P=0.004]. Tumors classed as Eastern Cooperative Oncology Group performance status 2 [adjusted hazard ratio (HR), 3.49; 95% CI, 1.10-11.03; P=0.033], stage II-IIIB tumors (adjusted HR, 2.55; 95% CI, 1.06-6.17; P=0.037) and the presence of a driver gene mutation (adjusted HR, 3.28; 95% CI, 1.55-6.94; P=0.002) were associated with a significantly reduced progression-free survival (PFS). Driver gene-targeted therapy was associated with an increased post-progression survival for patients that were reported to have disease progression (adjusted HR, 0.38; 95% CI, 0.16-0.91; P=0.030). There was no significant impact of driver gene mutation status on the overall survival (OS) of patients. Although the presence of a driver gene mutation was associated with an increased risk of disease progression and a reduced PFS, it was demonstrated that patients with disease progression may benefit from driver gene-targeted therapy, as patients with driver gene-targeted therapy had a similar OS compared with that of patients with a driver gene-negative or unknown status. Therefore, early comprehensive analysis of driver gene mutation status may be recommended for early-stage NSCLC cancer patients experiencing non-R0 resection.
