Associations between sleep metrics and serum periostin at baseline. a Severity of OSA and serum periostin (*p = 0.28 without adjustment for BMI, p = 0.07 with adjustment for BMI and b 3% ODI and serum periostin (**p = 0.03 without adjustment for BMI). High ODI was defined as 3% ODI ≥30.2/h, which was equivalent to the top 50% of the participants. OSA, obstructive sleep apnea; BMI, body mass index; 3% ODI, oxygen desaturation (≥3%) index
