Illustrations of trajectories identified in five previously published studies. Each trajectory is represented by mean values of the subgroup. Dunn 2013 is from [10], Axen 2011 is from [12], Kent 2012 is from [15] and Kongsted 2015 is from [11]. These papers were published as open access and therefore the authors hold the copyrights of the reprinted illustrations. Macedo [16]: The illustration was not published in the original paper and was provided by the author
