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: The aging population presents significant challenges to healthcare worldwide. Evidence concerning the safety and efficacy of neoadjuvant immunochemotherapy in patients with non-small-cell lung cancer (NSCLC) aged 70 years or older remains limited. Objectives: To investigate the safety and efficacy of neoadjuvant immunochemotherapy in NSCLC patients stratified by age into three groups, and to identify factors associated with overall survival (OS) and disease-free survival (DFS). Design: We performed a retrospective cohort study including 171 NSCLC patients with NSCLC who underwent neoadjuvant immunochemotherapy followed by surgical resection. The patients were categorized by age into three groups: ⩾70 years, 60-69 years, and <60 years. Methods: The safety and efficacy of neoadjuvant immunochemotherapy were comprehensively evaluated. Safety was assessed based on the incidence of treatment-related adverse events (AEs) and complications. Efficacy was determined through analyses of tumor response and survival outcomes. OS and DFS were analyzed using the Kaplan-Meier method, and independent prognostic factors were identified through the Cox proportional hazards model. Results: The study cohort comprised 24 patients aged ⩾70 years, 73 patients aged 60-69 years, and 74 patients under 60 years. OS and DFS did not differ significantly among the three age groups following neoadjuvant immunochemotherapy. Multivariate analysis identified major pathological response (MPR) as a significant independent predictor of OS (hazard ratio (HR): 0.232, 95% confidence interval (CI): 0.079-0.678, Conclusion: Neoadjuvant immunochemotherapy demonstrated consistent safety and efficacy across all age groups in this cohort of NSCLC patients. Achieving MPR was associated with improved OS and DFS, whereas the occurrence of postoperative complications was associated with diminished DFS.
