Dimensional scores of the PPS according to disease severity.

<p>Dimensional sub scores are expressed as percentage of the maximum possible score in the dimension (as indicated in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0022293#pone-0022293-t001" target="_blank">Table 1</a>, far left column).
