Reference probability and marginal effects of feeling unwell on day before interview (logistic regression, population averaged model).

*Reference case is a female subject age 30–39, 0–30 days on ART.aIndicates p-value ≤0.05 for Wald test that marginal effect equals marginal effect for 271–360 days on ART.bIndicates p-value >0.05 for Wald test that marginal effect equals marginal effect for 271–360 days on ART.

*参考案例为年龄30~39岁、接受抗逆转录病毒治疗（Antiretroviral Therapy, ART）时长0~30天的女性受试者。a表示：通过沃尔德检验（Wald test）验证该边际效应与抗逆转录病毒治疗时长271~360天组的边际效应相等时，所得p值≤0.05。b表示：通过沃尔德检验验证该边际效应与抗逆转录病毒治疗时长271~360天组的边际效应相等时，所得p值>0.05。
