The bivariate analysis between BMI and risk level of OSA showed significant results as well as neck circumference using both Berlin criteria (p<0.05) and STOP-BANG criteria (p<0.05). For gender, the result showed significant results with Berlin criteria (p<0.05) but insignificant with STOP-BANG criteria (p>0.05). Meanwhile, the results of the bivariate analysis between age, Mallampati score, alcohol consumption, and smoking showed insignificant results both with Berlin criteria (p>0.05) and STOP-BANG criteria (p>0.05).
