  • *Unadjusted but allowing for intracluster correlation in SEs.

  • †Net QALYs calculated using linear regression model adjusted for age, time since stroke, stroke severity, whether or not the carer had any long-term health conditions, cluster size and years of experience of the cluster staff.

  • QALYs, quality-adjusted life years.
