The Meta-analysis method will be used to comprehensively evaluate relevant literature on earthquake casualty estimation models, aiming to verify the effectiveness and reliability of existing models. Firstly, a systematic search will be conducted in both Chinese and English databases to select literature that includes information on sample size, evaluation factors, model types, and performance. Secondly, a random effects model is used to calculate the effect values included in the study, while the I2 statistic is used to test the level of heterogeneity. Finally, the robustness of the Meta-analysis results is assessed through bias analysis and sensitivity analysis. The results indicate that the overall evaluation performance of the model is good, but there is significant heterogeneity and publication bias among studies, mainly due to methodological differences. Sensitivity analysis shows that the Meta-analysis results are robust. In summary, the overall evaluation effect of the earthquake casualty estimation models is reasonable and the model performance is good, which can meet the actual needs of earthquake emergency response.
