图1 与SLE相关的主要危险因子筛选 Note： A. LASSO coefficient curves for 79 indicators according to log(λ). The colored lines represent the influence of λ value in the model on the weight coefficients of different indicators. The dashed line represents the best λ value and its number of indicators. B. Selection of the indicators by LASSO at the optimal parameter (λ). C. Multivariate Logistic regression analysis of major risk indicators. TP—total protein; Pos—positive; Neg—negative.
