Table 1 Inclusion criteria for eligible studies

- Population: At least 80% of the study participants were PLWD, informal and formal caregivers of PLWD, and/or practitioners caring for someone with dementia. This cut-off was based on proportion of PLWD among nursing home residents [17] and used by other published studies in Cochrane [18].

- Data: Decision-making process regarding nutrition and hydration interventions for PLWD; determinants, facilitators and barriers of the decisions

- Intervention: Any nutrition and hydration interventions, for example, oral- or hand-feeding, and enteral or parenteral ANH

- Setting: All settings in which decisions regarding nutrition and hydration for PLWD were made.

- Study design: Quantitative study, qualitative study, case study (case studies were included, because we expected that we could gain more insights into the whole decision-making experiences at an individual case.)
