Model estimated means of PIQ and PSQI.

Variable	Group	Baseline	Week 5	Week 12	Overall
PIQ	A	62.8	57.4	53.8	58.0
	B	61.3	59.4	56.2	59.0
	Overall	62.0	58.4	55.0	58.5
PSQI	A	9.2	9.8	7.7	8.9
	B	10.0	9.4	8.1	9.2
	Overall	9.6	9.6^	8.0^	9.0

Model estimated means from the linear mixed models for repeated measures with first-order autoregressive covariance structure. PIQ: Pain Impact Questionnaire; PSQI: Pittsburgh Sleep Quality Index. Pairwise comparisons using the Bonferroni adjustment indicated mean PIQ score at baseline were significantly higher than at week 12 ( = 0.003). ^Pairwise marginal means comparison using the Bonferroni adjustment showed that the overall mean PSQI score at week 5 was significantly higher than at week 12 ( = 0.04).
