  1. SLE Stressful life event; *p ≤ 0.05, **p ≤ 0.01.
  2. †N = 58 observations had missing values for AUDIT score and were therefore excluded. In the comparison of AUDIT score across education categories, an additional 12 observations were excluded due to missing values for the education variable. Similarly, an additional N = 136 observations for child SLE, N = 47 observations for adult SLE, and N = 4 for diagnosis of anxiety or depression were excluded in the respective comparisons.
