Additional file 2 of Comprehensive analysis and establishment of a prediction model of alternative splicing events reveal the prognostic predictor and immune microenvironment signatures in triple negative breast cancer

Additional file 2: The optimal PFS-related AS events was selected by LASSO regression for constructing the prediction models.

补充文件2：本研究通过LASSO回归（LASSO regression）筛选与无进展生存期（Progression-Free Survival, PFS）相关的最优可变剪接事件（Alternative Splicing events, AS events），以构建预测模型。
