*Earnings: pre-tax earnings including student allowances. Presented in 2005 values, in SEK 1000.
†Year of inclusion (T0) for PwMS: the year of first MS diagnosis. Year of inclusion (T0) for references: the year of inclusion to one of four panels. Estimates from Tobit models with lower bound set at zero (ie, no earnings).
‡Beta estimate.
↵§Differences significantly different from zero (p<0.05).
¶Time-invariant variables: measured at T0.
**Time-variant variables: measured at T0 or T+5.
