FIGURE 2.

Model of the mediating analysis of CA1 on the association between rapid eye movement (REM)–oxygen desaturation index (ODI) and verbal memory. The figure depicts the mediating effects of CA1 on the relationship between REM‐ODI and verbal memory performance. The model includes direct and indirect paths with corresponding path coefficients. The indirect effect through CA1 was significant (β = −0.096, p < 0.05). There was no significant effect of REM‐ODI on verbal memory (β = −0.007, p > 0.05). Indirect effect of REM‐ODI on verbal memory = −0.096, 95% confidence interval = −0.255 to −0.005. Significant paths were indicated by *.
