A comparative study of the efficacy and safety of PD-1/L1 inhibitor and platinum-containing dual-agent chemotherapy in patients with advanced non-small cell lung cancer resistant to EGFR-TKIs.

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
objectiveTo assess the efficacy and safety of combining Programmed Death-1/Programmed Death-Ligand 1 (PD-1/L1) inhibitors with platinum-containing chemotherapy for treating late-stage Non-Small Cell Lung Cancer (NSCLC) patients who have developed resistance to Epidermal Growth Factor Receptor-Tyrosine Kinase Inhibitors (EGFR-TKIs).
methodsA retrospective analysis was conducted at Baoji Traditional Chinese Medicine Hospital involving 133 patients with advanced NSCLC who had shown resistance to EGFR-TKIs and were treated from October 2018 to May 2021. The cohort was categorized into two groups: one treated with immune checkpoint inhibitors (ICIs) plus chemotherapy and antiangiogenic agents (ICIs+BCP group), and the other treated with ICIs alone (ICIs group). Baseline data collected included demographic factors, smoking status, PD-L1 Tumor Proportion Score (TPS), EGFR mutation, Eastern Cooperative Oncology Group (ECOG) score, and routine blood markers prior to second-line therapy. Computed Tomography (CT) scans were performed every two treatment courses to evaluate the treatment efficacy.
resultsThe ICIs+BCP group exhibited a statistically significant improvement in Overall Survival (OS) compared to the ICIs group (P=0.001). Cox survival analysis uncovered age (P=0.012), PD-L1 TPS expression (P<0.001), treatment regimen (P=0.006), Neutrophil-to-Lymphocyte Ratio (NLR) (P=0.024), and Platelet-to-Lymphocyte Ratio (PLR) (P=0.005) as independent factors influencing OS in patients with advanced NSCLC resistant to primary-line EGFR-TKI therapy. The nomogram model, based on these prognostic factors, exhibited Area Under the Curve (AUC) values of 0.823 and 0.769, indicating its predictive accuracy for 1-year and 2-year survival, respectively.
conclusionCombining ICIs with BCP prolongs OS in patients with NSCLC resistant to EGFR-TKIs. This study underscores the importance of personalized treatment plans and biomarker evaluations to improve outcomes in drug-resistant cases.
