Conclusion
dementia
The HOMESIDE trial is the first randomised controlled trial to examine a home-based music intervention delivered by a caregiver to manage behavioural and psychological symptoms for people living with dementia. It is an international multi-country study, increasing the generalisability of the findings. The intervention training and assessment were transferred to be online due to the COVID-19 pandemic, restricting participation only to those with internet access. The development of a detailed statistical analysis plan prior to unmasking will reduce the potential for bias and improves transparency.
