The influence of demographic factors such as sex and smoking history on the efficacy of ICIs has been the focus of extensive research. Some concluded that there is no statistically significant difference in ICI efficacy between smokers and non-smokers. However, some systematic reviews suggest that smokers may derive greater benefit from ICI therapy. This observation is likely attributable to the fact that patients with a smoking history often exhibit a higher tumor mutational burden (TMB), which is associated with enhanced ICI efficacy. On the other hand, the impact of sex on ICI effectiveness remains unclear, with conflicting results reported in the literature. Specifically, some studies suggest greater efficacy in male patients, while others indicate a more pronounced benefit in female patients.
The debate surrounding the influence of sex and smoking history on ICI efficacy remains unresolved. One potential explanation for these conflicting findings is that the effects of sex and smoking history may vary depending on the specific treatment regimen used. ICIs can be administered as monotherapy, in combination with platinum-based chemotherapy, or alongside CTLA-4 inhibitors, each with distinct mechanisms of immunological action.
In this study, we aim to evaluate the impact of sex and smoking history on overall survival (OS) hazard ratios (HR, HRos) in patients with advanced NSCLC treated with ICIs across all treatment regimens. Specifically, we seek to clarify how different treatment regimens influence the effects of sex and smoking history on patient survival.

Patients
This study will include patients with advanced non-small cell lung cancer (NSCLC), encompassing metastatic, relapsed, and locally advanced diseases.
adenocarcinoma, squamous cell carcinoma, large cell carcinoma, and non-squamous cancers are considered eligible. Studies exclusively targeting large cell neuroendocrine carcinoma (LCNEC) will be excluded.
Treatment
The experimental regimens must contain immune checkpoint inhibitors (ICIs), including PD-1 inhibitors, PD-L1 inhibitors, or CTLA-4 inhibitors. LAG-3 inhibitors will be excluded as no phase III trials are available at the time of the search. The analysis will include ICI monotherapy, dual ICI combinations, and ICIs combined with cytotoxic therapies. Both first-line and subsequent lines of therapy will be eligible.
The control regimens must consist of cytotoxic therapies, placebo, or best supportive care. Molecular targeted therapies and ICIs must not be included in the control regimen. Based on the treatment regimens, studies will be categorized into three groups: (1) platinum-doublet chemotherapy plus one PD-(L)1 inhibitor, (2) ICI monotherapy, and (3) regimens containing CTLA-4 inhibitors.
Study design and reporting style
This study will include phase III trials (or phase II/III trials) published as full research article.

Statistics
The rate of hazard ratio (RHR) will be calculated using HRs for sex and smoking history subgroups, based on the formula below: RHR = HRos_men / HRos_women. The 95% confidence interval for the RHR will be derived using the following SE: SE_RHR = (SE_men^2 + SE_women^2)^.5. The RHR for smoking history will be calculated similarly, using non-smokers as the reference.
Meta-analyses will be conducted using RevMan version 5.4.1. The choice between fixed-effect and random-effects models will be determined based on overall heterogeneity. Subgroup heterogeneity will be a key focus of our analysis. Heterogeneity will be assessed using the I2 statistic and the P-value for heterogeneity.
