Missing rate <5% with random missing: Adopt the complete case analysis method; 2. Missing rate of 5%-20%: Adopt the multiple imputation method (MICE, 5 imputed datasets, chained equation method); 3. Missing rate of key outcome indicators (PFS/OS) >20%: Conduct sensitivity verification using the worst-case analysis method; 4. Missing data due to withdrawal caused by adverse events: Record as treatment failure without any imputation;Abnormal data processing: 1. Identification: Screen outliers using the ±3SD method or Grubbs test (α=0.05); 2. Processing: First verify whether there are measurement/recording errors and make corrections if any; Adopt the Winsorizing method (with P99/P1 as the upper and lower limits) for genuine outliers, and compare the results before and after processing in the sensitivity analysis;Data statistical methods: 1. Quantitative data: Use mean ± standard deviation (x±s) for normally distributed data, and median (interquartile range) [M (P25,P75)] for skewed distributed data; 2. Categorical data: Frequency (percentage) [n (%)], and use the chi-square test/Fisher's exact test for inter-group comparison; 3. Survival analysis: Kaplan-Meier method; 4. Multivariate analysis: Logistic regression/Cox proportional hazard regression/multiple linear regression, etc.;Censored data processing: For subjects without disease progression or death, the last follow-up data are included in the survival analysis as censored values.
