The interaction between SUA levels > 5 mg/dL and female sex for moderate to severe sleep-disordered breathing. The squares represent the odds ratio for males, and the diamonds represent the odds ratio for females. The yellow arrow and dashed line indicate the odds increase for moderate to severe sleep-disordered breathing due to serum uric acid ≥ 5 mg/dL. The brown arrow represent the odds ratio for moderate to severe SDB, which significantly increases due to the interaction between female sex and serum uric acid ≥ 5 mg/dL. sUA, serum uric acid; MS-SDB, moderate to severe sleep-disordered breathing.
