  1. Four patients with dementia-associated parkinsonism excluded from this Table 2 participants with PD, 2 with DLB, 2 with PSP, and 3 with vascular parkinsonism excluded from median time and incidence rate analysis because they had delirium during an hospital admission during which they were diagnosed with a parkinsonian syndrome.
  2. CI confidence interval, ND not defined, NR not reached.
