Figure 2: Percentages for each time period (0–3 months/4–6 months/7–9 months/10–12 months/over 13 months) that AD and VaD patients spent at each GCI stage. Mean duration for each GCI stage (month). AD: Alzheimer’s disease; VaD: vascular dementia. Number in the figure is the number of the patients in each time period. As the GCI stage increased, patients in both groups spent a longer duration in each of the subsequent periods. However, there was no significant difference between the two groups in the duration of any of the GCI stages.
