aQoL-AD: Quality of Life-Alzheimer’s Disease scale (total score ranges from 13 to 52, higher scores indicate better QoL); effect estimation by linear mixed model.
bCMAI: Cohen-Mansfield Agitation Inventory (total score ranges from 25 to 175, higher scores indicate higher frequencies of manifestations).
cAntidepressants, anxiolytics and acetylcholinesterase inhibitors.
dBedrails, fixed tables, belts in bed or chair, other physical restraints.
ICC=intra-class correlation coefficient.
