Fig. 3From: Breathing cessation events that compose the apnea–hypopnea index are distinctively associated with the adverse outcomes in Alzheimer’s diseaseCognitive decline according to the first component of the PLS regression analysis. Lower values of the first component of the PLS (X-axis) represent a higher number of hypopneas. Lower values of change in MMSE at the 12-month follow-up (Y-axis) represent a greater decrease in MMSE at the 12-month follow-up (i.e., higher cognitive decline).
