*Age is significantly different between all clusters except Clusters 2–3 and 2–4.
**The frequency of concurrent AD is significantly different between Cluster 2–2 and all other clusters.
***The frequency of clinical diagnosis is significantly different between Clusters 2–1 and 2–2; and Clusters 2–2 and 2–3. Pairwise comparison is done using Bonferroni correction.
