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
The present multicenter study was performed to compare the efficacy of epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) monotherapy with that of combined EGFR-TKI plus vascular endothelial growth factor receptor (VEGF) inhibitor/cytotoxic therapy in patients with programmed death-ligand 1 (PD-L1)-positive EGFR-mutant non-small cell lung cancer (NSCLC). Data from patients with PD-L1-positive EGFR-mutant NSCLC were collected from 12 institutes. Survival in patients treated with first- and second-generation EGFR-TKIs, osimertinib (third-generation EGFR-TKI), and combined EGFR-TKI plus VEGF inhibitor/cytotoxic therapy was analyzed by multiple regression analysis with adjustments for sex, performance status, EGFR mutation status, PD-L1 expression level, and the presence or absence of brain metastasis using a Cox proportional hazards model. Data from a total of 263 patients were analyzed, including 111 (42.2%) patients who had received monotherapy with a first- or second-generation EGFR-TKI, 132 (50.2%) patients who had received osimertinib monotherapy, and 20 (7.6%) patients who had received combined EGFR-TKI plus VEGF inhibitor/cytotoxic therapy (hereafter referred to as combined therapy). Multiple regression analysis using the Cox proportional hazards model showed that the hazard ratio (95% confidence interval) for progression-free survival was 0.73 (0.54-1.00) in the patients who had received osimertinib monotherapy and 0.47 (0.25-0.90) in patients who had received combined therapy. The hazard ratio for overall survival was 0.98 (0.65-1.48) in the patients who had received osimertinib monotherapy and 0.52 (0.21-1.31) in patients who had received combined therapy. In conclusion, combined therapy was associated with a significant reduction in the risk of progression compared with first- and second-generation EGFR-TKI monotherapy, and therefore, may be promising for the treatment of patients of NSCLC.
