From: Association between low-dose pulsed intravenous cyclophosphamide therapy and amenorrhea in patients with systemic lupus erythematosus: A case-control study

  1. *p values and ORs were determined by stepwise multivariate logistic regression using a model adjusted for the following variables: 'Age ≥ 40 years-old'; IVCY; maximum dose of prednisolone; steroid pulse therapy; SLEDAI-2K.
  2. IVCY intravenous cyclophosphamide, SLE systemic lupus erythematosus, OR odds ratio, CI confidence interval.
