The sentences
Despite the observed heterogeneity across studies, the overall effects for PFS ( Z = 2.14, p = 0.03) and OS ( Z = 1.99, p = 0.05) were marginally significant, suggesting a potential benefit of monotherapy over combined therapy for both survival outcomes.
Moreover, monotherapy showed a trend toward superior PFS and OS compared with combined therapies, albeit not statistically significant, suggesting the potential of monotherapy to optimize GBM treatment strategies (Yamaguchi et al. 2021 ).
