<p>SPRTBA for categorical variables or logistic regression for continuous variables (‘Age’, ‘NSMP’ and ‘Unprotected NSMP’) p-values between seed variables and the selected variables by country.</p>

SPRTBA for categorical variables or logistic regression for continuous variables (‘Age’, ‘NSMP’ and ‘Unprotected NSMP’) p-values between seed variables and the selected variables by country.针对分类变量采用SPRTBA方法，针对连续变量（年龄(Age)、NSMP、非保护性NSMP(Unprotected NSMP)）采用逻辑回归(logistic regression)方法，按国家计算种子变量与选定变量之间的p值(p-values)。
