Figures are modelled parameter estimates (95% confidence intervals).
BL1 = indicator for baseline 1; BL2 = indicator for baseline 2; BL3 = indicator for baseline 3; T6 = indicator for t = 6 months after start of intervention; T12 = indicator for t = 12 months after start of intervention; iv = indicator for intervention group; T6iv = interaction between T6 and iv; T12iv = interaction between T12 and iv.
