Efficacy and safety of serplulimab in solid tumors: a meta-analysis.
Synthesis in Frontiers in pharmacology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objective: The goal of this study was to investigate the effectiveness and safety of serplulimab in advanced solid tumors through a meta-analysis approach. Methods: An electronic search was conducted across the Embase, Web of Science, PubMed, and Cochrane Library databases, covering the period from each database's inception through 6 May 2025. Meta-analysis and related analyses, including subgroup, sensitivity, and publication bias assessments, were performed using Stata 16.0. The Cochrane Risk of Bias Assessment Tool (version 5.1.0) was utilized to measure the quality of randomized controlled trials (RCTs). For single-arm studies, quality was evaluated using the Methodological Index for Non-Randomized Studies (MINORS). Results: Ten studies, including three RCTs and seven single-arm studies, were analyzed, involving 2,020 patients. In the analysis of RCTs, serplulimab significantly elevated overall survival (OS) [HR = 0.68, 95% CI: 0.59-0.79, P < 0.01], disease control rate (DCR) [RR = 1.04, 95% CI: 1.01-1.08, P < 0.05], progression-free survival (PFS) [HR = 0.53, 95% CI: 0.47-0.61, P < 0.01], and objective response rate (ORR) [RR = 1.30, 95% CI: 1.09-1.56, P < 0.01]. The analysis of single-arm studies revealed that the ORR for serplulimab in solid tumors was [ES = 45%, 95% CI: 31%-59%, P < 0.01], and the DCR was [ES = 71%, 95% CI: 63%-80%, P < 0.01]. Among the ten studies, the most common adverse events included reductions in platelet count (0.32, 95% CI: 0.20-0.43), white blood cell count (0.30, 95% CI: 0.17-0.44), anemia (0.29, 95% CI: 0.09-0.48), and proteinuria (0.28, 95% CI: 0.17-0.38). Conclusion: Based on current research, serplulimab appears to be effective for solid tumors. However, given the limitations of the studies, for example, possible selection bias in single-arm studies, further multicenter, high-quality, large-sample RCTs are necessary to validate this conclusion.
