4. Assessment between PSG monitoring results and A/N ratio
The findings revealed that the A/N ratio was correlated with the OAHI
(r=0.275, p =0.000), ODI (r=0.227, p =0.000) and
LSaO2 (r=-0.225, p =0.000). Additionally, the A/N
ratio was correlated with the OAHI (r=-0.208, p =0.010), ODI
(r=0.183, p =0.023), and LSaO2 (r=-0.202,p =0.012) in the A/N≥0.80 group. However, there were no
significant associations between the A/N ratio and the OAHI, ODI, or
LSaO2 in the other groups.(Table 4)
