^aLoss of significance after statistical control: the independent variable Duration of care allowance of current dependency level lost statistical significance when modelled with the variables Duration of care allowance and Care dependency level (F(df = 6) = 9.148, ) and was eliminated. ^bLoss of significance after statistical control: the independent variable Travel time to cared-for-person lost statistical significance when modelled with the variable Time spent on care (F(df = 4) = 1.457, ) and was eliminated. When assessing the interaction between variables and their effect on caregiver burden, the variable Time spent on care was statistically significant (F(df = 1) = 34.223, ) and was considered for further data modelling. ^cConsidered conceptually relevant after discussion in the research team.
