  7. € Adjusted for baseline values and age, gender, education level, employment status, Socio Economic Index For Areas, and Region; presents marginal means (or mean differences) with 95% Confidence Interval (CI) from linear mixed models that control for repeated measures and adjust for potential confounders, with the outcome time points of 6-months and 12-months. Models are limited to participants with data for at least one follow-up (i.e. either 6-months, 12-months or both).
