Model Statistics:	Model χ2(12) = 58.58, p <.001 Percent correctly classified: 64.5% Nagelkerke’s R2 = .20

Note. SQ = Sleep Quality; AOR = adjusted odds ratio; CI = confidence interval; ref. = referent.

Medication adherence assessed at study screening and 12-month follow-up using a 3-item self-report measure (Wilson et al., 2016).

Bolded results are significant at p <.05 or less.
