Table 4 Changes in MET-min per day over time before and after starting work, showing adjusted interactions with different individual and job characteristics. Initial slope shows baseline trend per year before employment transition, transition into work shows change in intercept immediately after starting work, and change in slope after starting work shows longer-term trends in MET-min per day each year after starting work
