^aThese probabilities are the main trajectories represented within each class (p>.10).

^bValues represent the mean for each class.

^cProbability of belonging to each class. The percentages indicated refer to this probabilistic approach but do not represent a proportion of individuals.

^dCumulative over the 6-month period.

^eAt the time of publication, a currency exchange rate of €1=US $1.084 was applicable.
