Nevertheless, associations between MRS-CRP and REI (0.91 [0.22, 1.61]), mean SpO2 (−0.08 [−0.14, −0.01]), long sleep duration (OR = 1.30 [1.06, 1.06]), diabetes (OR = 2.46 [2.02, 3.00]) and hypertension (OR = 1.28 [1.09, 1.52]) remain statistically significant, with minimal changes observed for metabolic comorbidities (Figure S9). Here, CRP is linked to diabetes mellitus.
