PD-L1 Negative Advanced Non-Small Cell Lung Cancer: Practice Patterns and Real-World Outcomes.
Article in Current oncology (Toronto, Ont.), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 standard first-line treatment for metastatic non-small cell lung cancer (NSCLC) without oncogenic alterations and programmed death-ligand 1 (PD-L1) expression < 1% is a combination of chemotherapy (CT) and immunotherapy (IO). However, real-world overall survival (OS) appears more modest than in clinical trials, averaging 10-13 months. This retrospective study aimed to assess treatment patterns and real-world outcomes at the Institut universitaire de cardiologie et de pneumologie de Québec (IUCPQ). Patients diagnosed between January 2019 and December 2023 with advanced PD-L1 <1% NSCLC and treated with palliative intent at IUCPQ were included and categorized by first-line treatment. Progression-free survival (PFS) and OS of the CT + IO and CT groups were compared using Kaplan-Meier curves and Cox regression analyses. Data regarding regimen selection, adverse events and subsequent treatment lines were collected. Among 217 eligible patients, 82 (37.8%) received CT + IO, 32 (14.7%) CT alone, 16 (7.4%) targeted therapy, and 87 (40.1%) supportive care. Median PFS was 5.3 vs. 4.7 months (
