Comparative Efficacy and Safety of Immunotherapy on Non-Small Cell Lung Cancer Patients With Brain Metastases: A Systematic Review and Network Meta-Analysis.
Synthesis in The clinical respiratory journal, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundGrowing evidence suggests that immunotherapy has a positive effect on non-small cell lung cancer (NSCLC) patients with brain metastases (BMs). However, it remains unclear which type of immunotherapy is more efficient. The aim of this network meta-analysis (NMA) was to compare the efficacy and safety of different immunotherapy types and determine the optimal option.
methodFour databases (PubMed, Cochrane Library databases, Embase, and Web of Science) and ClinicalTrial.gov were searched from inception until January 26, 2023. Randomized controlled trials (RCTs), prospective nonrandomized trials, or observational studies investigating NSCLC patients with BMs treated by immunotherapy were included. The quality of the included studies was evaluated using the Cochrane risk of bias (ROB) tool and the Newcastle-Ottawa Scale (NOS). The efficacy of immunotherapy on NSCLC patients with BMs was evaluated using frequentist random-effects NMA.
resultEleven studies from 1560 citations, encompassing 1437 participants, were included in this NMA. Statistical analysis showed that pembrolizumab (SMD = 4.35, 95% CI [2.21, 6.60]) and nivolumab+ipilimumab (SMD = 3.81, 95% CI [1.21, 6.40]) could improve overall survival (OS). Pembrolizumab (SMD = 3.32, 95% CI [2.75, 3.90]) demonstrated better effects in improving the overall response rate (ORR). No significant difference in adverse event (AE) was observed between immunotherapy and chemotherapy.
conclusionOur findings indicated that pembrolizumab was the most promising immunotherapy for NSCLC patients with BMs. Nivolumab+ipilimumab might be an alternative choice to improve OS. LIMITATION: Inconsistency tests were not performed because of the scarcity of direct comparison. Besides, high heterogeneity was observed in our NMA.
