Pembrolizumab and Pemetrexed for Older Patients With Nonsquamous NSCLC and Programmed Cell Death-Ligand 1 Tumor Proportion Scores of Less Than 50.
Article in JTO clinical and research reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04396457 (Phase 2 Study of Pembrolizumab Plus Pemetrexed for Elderly Patients With Non-squamous Non-small Cell Lung Cancer With PD-L1 Tumor Proportion Score of Less Than 50%), which is not on this map.

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

Abstract
Introduction: Pembrolizumab with pemetrexed and cisplatin/carboplatin is an approved first-line treatment for metastatic nonsquamous NSCLC. Nevertheless, its efficacy and safety in patients aged 75 years and above remain unclear. We assessed the efficacy and safety of pembrolizumab with pemetrexed in patients with programmed cell death-ligand 1 expression tumor proportion scores of less than 50%. Methods: This multicenter, open-label, phase 2 trial involved 42 institutions across Japan. Eligible participants had metastatic or recurrent nonsquamous NSCLC without sensitizing Results: Forty-nine patients were enrolled in this study between July 2020 and May 2022. The objective response rate was 36.7% (95% confidence interval [CI]: 23.4%-51.7%). The disease control rate was 65.3% (95% CI: 50.4-78.3%). The median progression-free survival was 7.6 months (95% CI: 4.8-16.2), and the median overall survival was 19.4 months (95% CI: 11.8 mo-unreached). The most common grade 3 or 4 adverse events were neutropenia (31.3%), leukopenia (20.8%), and anemia (12.5%). No treatment-related deaths occurred during this period. Conclusions: Pembrolizumab with pemetrexed is a promising first-line treatment option for older patients with metastatic nonsquamous NSCLC. This trial was registered at ClinicalTrials.gov (NCT04396457) and the Japan Registry of Clinical Trials (jRCTs041200012).
