RAM=remote automated monitoring; IQR=interquartile range; NR=not reported; SD=standard deviation.

^*Using modified Poisson model.

^†Calculated from crude proportions.

^‡A stable relative risk estimate based on a modified Poisson regression was not possible because of too few events.

^§Based on normal approximation to Poisson.

^¶In the virtual care group 85.6%, 89.1%, 91.1% of patients provided data at 7, 15, and 30 days after randomisation, respectively. In the standard care group 93.6%, 91.2%, 90.9% of patients provided pain data at 7, 15, and 30 days after randomisation, respectively.
