  • *Complete case analysis. Not all individuals contributed sufficient data in the 2-week period preceding the clinic date to calculate a mean number of scans.

  • †Primary care prescribing estimated based on BG test strip and flash monitoring sensor usage, based on mean number of readings in preceding 2-week period.

  • ‡Units unadjusted other than for variable follow-up; costs are mean per person year costs based on individual patient data.

  • §Linear prediction via a two-level mixed model adjusting for variance difference between patients in terms of IMD, time since diagnosis, age, test modality (point of care or laboratory).

  • IMD, index of multiple deprivation; NA, not available; NHS, National Health Service; SMBG, self-monitoring of blood glucose.
