Efficacy of first-line immune checkpoint inhibitor and anti-angiogenic agent combination therapy for Kirsten rat sarcoma viral antigen-mutant advanced non-small-cell lung cancer: a systematic review and network meta-analysis.
Synthesis in Thoracic cancer, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
backgroundRecent advancements in advanced non-small-cell lung cancer (NSCLC) treatment have significantly improved primary therapy outcomes owing to the emergence of various molecular targeted therapies and immune checkpoint inhibitors (ICIs). However, for Kirsten rat sarcoma viral antigen (KRAS) mutations, molecular targeted drugs, such as sotorasib, are not applicable as first-line treatments, and the optimal primary treatment remains unclear. Therefore, we aimed to investigate the efficacy of ICI combination therapy as first-line treatment for KRAS-mutant NSCLC.
methodsWe conducted a systematic search for phase 3 randomized controlled trials (RCTs) that presented data on KRAS mutation status in advanced NSCLC. The primary endpoints were progression-free survival (PFS) and overall survival (OS). A random-effects network meta-analysis was conducted to perform direct and indirect comparisons among treatment groups.
resultsSix RCTs were eligible for inclusion. In the network meta-analysis for KRAS-mutant NSCLC, Chemo + bevacizumab (Bev) + ICI was associated with improved PFS (hazard ratio [HR] 0.38, 95% confidence interval [CI] 0.22-0.64), followed by Chemo + ICI + ICI (HR 0.66, 95% CI 0.47-0.93) and Chemo + ICI (HR 0.67, 95% CI 0.49-0.91). The most beneficial effect on OS was observed with Chemo + Bev + ICI (HR 0.50, 95% CI 0.34-0.73), followed by Chemo + ICI + ICI (HR 0.64, 95% CI 0.48-0.87) and Chemo + ICI (HR 0.72, 95% CI 0.56-0.92). Regarding OS in wild-type KRAS, ICI + ICI (HR 0.73, 95% CI 0.50-1.07) produced the most favorable effects, followed by Chemo + ICI (HR 0.79, 95% CI 0.63-0.99).
conclusionThe efficacy of Chemo + Bev + ICI is potentially high for improving PFS and OS in KRAS-mutant NSCLC. In advanced NSCLC, the presence or absence of KRAS mutations may need to be considered when administering first-line treatment.
