Linear mixed-effects model with an unstructured variance–covariance structure for the random effects, modelled against group, outcome score at baseline, minimisation factors (baseline ISI score, region, age, use of prescribed sleep-promoting medication, sex and baseline PHQ-9 score), assessment time point, an indicator variable for if the participant’s 6-month assessment time point was (or would have been, if the participant withdrew or was lost to follow-up) before or after the UK went into a national lockdown (23 March 2020), and an interaction between randomised group, assessment time point, and the pandemic indicator variable as fixed effects; GP practice as a random effect, and a random intercept for each participant.
