Safety and efficacy of PD-1/PD-L1 immune checkpoint inhibitors in patients with pre-treated advanced stage malignant mesothelioma: a systematic review and meta-analysis.
Synthesis in BMC cancer, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundMalignant mesothelioma is an aggressive cancer with poor prognosis. Programmed cell death protein-1 (PD-1) and its ligand 1 (PD-L1) immune checkpoint inhibitors (ICIs) have recently presented as a viable option in some first line but primarily as a second-line treatment of advanced-stage malignant mesothelioma (asMM). Therefore, this systematic review and meta-analysis aims to assess the safety and efficacy of PD-1/L-1 ICIs in advanced-stage malignant mesothelioma.
methodsPubMed, Scopus, and Cochrane databases were searched for all studies assessing the safety and efficacy of anti PD-1/PD-L1 agents. Primary outcomes were objective response rate (ORR) and disease control rate (DCR). Secondary outcomes were median progression free (mPFS) and overall survival (mOS). Safety outcomes were treatment- (TRAEs) and immune-related adverse events (IRAEs). A random-effects meta-analysis was performed to pool medians and to derive event rates.
resultsA total of 15 studies were included with total of 1064 asMM patients. ORR and DCR were 16% and 57%, respectively. A pooled mPFS was 4.53 (CI: 3.40-5.65) and mOS was 10.51 (CI: 9.03-12.00). Overall TRAEs had an event rate of 0.69 (0.50-0.83) whereas IRAEs had an event rate of 0.28 (0.15-0.46). There were no significant differences between pembrolizumab, nivolumab primarily, and avelumab subgroups for all the outcomes. Additionally, meta-regression found no covariate to be a significant factor in ORR and DCR.
conclusionIn this meta-analysis we found that anti-PD1/PD-L1 treatment could be useful in pretreated asMM as they had at least comparable or greater mPFS, mOS, ORR, and DCR than other second-line agents currently being used.
