Study	Reason for exclusion
Cheston 2007	This trial was not randomised or quasi‐randomised. Participants were offered a choice of interventions: "Two control conditions were used creating an A1, B, A2, C, A3 and A1, C, A2, B, A3 design, in which A represents a baseline condition (usual care/no intervention), B represents the SPT intervention and C is the opportunity to listen to a favourite music tape. The order in which the SPT and music conditions were offered to participants alternated."
Evans 2016	This study aimed to collect information about the way in which Personal Message cards were used as an alternative method of delivering Simulated Presence therapy. This was not an intervention study.
Kajiyama 2007	In this study SPT was evaluated as presentation of old photographs and favourite music pieces of individuals with dementia, combined in personalized video channels via a television monitor in 23 subjects with Alzheimer disease. However, insufficient information was provided as to how the participants were allocated between the groups or whether the study was a cross‐over trial.
Miller 2001	A pretest‐post test quasi‐experimental design that evaluated simulated presence therapy.
O'Connor 2011	The study evaluated simulated presence therapy for 1 participant (N‐of‐1 trial).
Peak 2002	N‐of‐1 trial of 4 cases.
Smith 2010	An abstract of a protocol only.
Woods 1995	A pretest‐posttest quasi‐experimental design that evaluated simulated presence therapy.
Zetteler 2008	A systematic review that considered simulated presence therapy for people with dementia.
