Do age and performance status matter? A systematic review and network meta-analysis of immunotherapy studies in untreated advanced/metastatic non-oncogene addicted NSCLC.

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: Immune checkpoint inhibitors (ICIs) redefined the treatment of non-small cell lung cancer (NSCLC) but their efficacy in elderly and frail patients remains unclear due to immune-senescence and the underrepresentation of these populations in clinical trials. This systematic review and meta-analysis aimed to evaluate and rank first-line ICI-based therapies in NSCLC, stratified by age and performance status (PS). Methods: A comprehensive search for randomized controlled trials (RCTs) of ICI regimens, pairwise and network meta-analyses (NMA) based on age (<65, ≥65, ≥75 years) and PS (0 vs. 1) were conducted. Endpoints were overall survival (OS) and progression-free survival (PFS). Results: ICIs significantly improved OS and PFS versus chemotherapy (CT) in most subgroups. No OS benefit was observed in patients over 75 years. In younger patients, ICI+CT combinations (e.g. pembrolizumab+CT, cemiplimab+CT, camrelizumab+CT) ranked highest for OS and PFS. Among ≥65y patients, cemiplimab ranked first reaching statistical significance in most comparisons, while pembrolizumab was the most effective option for PFS. Stratified by PS, cemiplimab+CT ranked highest for OS in PS 0 patients, whereas cemiplimab was preferred in PS 1 patients. Overall, combination regimens were more effective in younger/fit patients, while monotherapy was more effective in older/PS 1 patients, suggesting a different benefit-risk balance. Anti-PD-1 therapies (alone or in combination) outperformed anti-PD-L1 and anti-CTLA-4 therapies in OS. Conclusions: This meta-analysis highlights how the efficacy of ICIs in advanced NSCLC varies by age and PS. These findings support a tailored approach to immunotherapy and emphasize the need for trials specifically targeting frail and elderly populations.
