Synopses of epidemological studies connecting gout with OSA

ReferencesDescription of studyNumber of participantsResultsRisk ratio

OSA: 4.9% with gout. Incidence rate 7.83/KPyr

No OSA: 2.6% with gout. Incidence rate 4.03/KPyr

Kanbay et al. [15], 2014All participants tested for OSA, and questioned about history of cardiovascular disease.72 Controls (AHI < 5); 47 mild (5 < AHI < 15); 75 moderate OSA (15 < AHI < 30); 192 severe (AHI > 30)SUA data show monotonic increase with AHI in those who had a cardiovascular eventN/A

* Not all subjects were tested for OSA so the numbers are likely to underrepresent the true number of subjects with OSA. SA: sleep apnea; BMI: body mass index; AHI: apnea-hypopnea index; KPyr: kiloperson-years; N/A: not applicable; SUA: serum uric acid
