Table 3.

Simple slope analyses revealed that stress-related increases in IL-6 and IL-6/IL-10 ratio varied as a function of PSQI global sleep quality scores at high visceral adiposity (+1 SD mean sagittal diameter) with steeper increases observed among poor sleepers. All analyses adjusted for age, number of medical comorbidities, and caregiver status.

Outcome: IL-6 trajectory	B₀(SE)	p-value	B_time (SE)	p-value
Poor sleepers (+1 SD PSQI)	2.79 (0.50)	<0.001	1.86 (0.24)	<0.001
Average sleepers (mean PSQI)	2.43 (0.50)	<0.001	1.42 (0.18)	<0.001
Good sleepers (−1 SD PSQI)	2.08 (0.69)	0.004	0.97 (0.26)	<0.001
Outcome: IL-6/IL-10 trajectory
Poor sleepers (+1 SD PSQI)	1.33 (0.50)	0.011	1.47 (0.22)	<0.001
Average sleepers (mean PSQI)	0.92 (0.51)	0.076	0.85 (0.15)	<0.001
Good sleepers (−1 SD PSQI)	0.52 (0.74)	0.489	0.22 (0.22)	0.321
