Efficacy of immune checkpoint inhibitors in younger patients with non-small cell lung cancer.
Article in Journal of cancer research and clinical oncology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
purposeBecause patients younger than 40 years are rarely enrolled in clinical trials in non-small cell lung cancer (NSCLC), their survival benefit of immune checkpoint inhibitors (ICIs) needs to be clarified.
methodsThe National Cancer Database was queried for patients who were diagnosed with stage IV NSCLC between 2016 and 2018. ICIs were administered in the first-line setting. The overall survival (OS) of patients with stage IV NSCLC according to the receipt of ICIs was compared in different age groups (< 40, 40-49, 50-59, 60-69, 70-79, and ≥ 80 years). Multivariate analyses identified the clinical characteristics predictive of OS. Propensity score matching (PSM) was conducted to reduce the biases arising from clinical characteristics.
resultsThis study included 126,476 patients with stage IV NSCLC. In univariate analysis, ICI treatment was not associated with a survival benefit in patients younger than 40 years with stage IV NSCLC relative to their ICI-naïve counterparts after PSM (median OS: 24.2 months vs. 24.0 months, hazard ratio [HR] = 1.01, 95% confidence interval [CI] = 0.81-1.27, P = 0.9031). Multivariate analysis revealed that ICI use was not an independent predictor of OS in patients with stage IV NSCLC < 40 years old (HR = 0.96, 95% CI = 0.76-1.21, P = 0.7230). Sequential improvement of the HR was observed with increasing age.
conclusionOur study suggested a poor survival benefit of ICIs in stage IV NSCLC patients younger than 40 years old, which should be validated in prospective studies.
