M = Medium: the quality of methods used in this paper permits the results, within the scope of the study design, to be interpreted, but with some caution. L = Low: the quality of methods used in this paper urges the reader to interpret the results, even within the scope of the study design, with sufficient caution.</p><p>£See <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0066485#pone.0066485.s002" target="_blank">Table S2</a>.</p>**<p>The ‘B’ statement expresses whether the study supported the existence of exogenous boosting (‘+) or not (‘−’).</p
