Data from the total cohort presented collectively and sub-stratified by first clinic type: face-to-face or virtual. The mean and standard deviation (SD) of patient age at the initial appointment (baseline), index of multiple deprivation (IMD) decile, and index of deprivation affecting older people (IDAOP) decile were compared. Wilcoxon signed-rank test was used for comparison of face-to-face and virtual-clinics sub-cohorts. The Chi-square test was used for categorical comparison i.e., gender and ethnicity.
