*The coefficients represent the effect of a unit change in the independent variable on the odds of preferring a specialty. Numbers in brackets below each coefficient are 95% CI.

†Attribute values normalised to range from 0 to 10, so that each unit corresponds to 10%.

‡Attribute values normalised so that each unit corresponds to €10 000.

§Binary variable equal to 1 when the student's preferred specialty is also his favourite specialty.

¶Number of students with data on all explanatory variables in the model.

**Number of specialty choices with data on all explanatory variables in the model.
