“…Correlations between TAS-20 and LEAS have consistently been negative, albeit not significant (Simson et al, 2002 ; Bydlowski et al, 2005 ; Subic-Wrana et al, 2005 ; Parling et al, 2010 ; Baker et al, 2014 ; Lane et al, 2015a ). For healthy participants (including healthy controls) the results have been mixed, with a few studies showing positive correlations (Lundh et al, 2002 ; Waller and Scheidt, 2004 ; Bydlowski et al, 2005 ) although most studies show a negative association (Lane et al, 1998b ; Subic-Wrana et al, 2001 ; Lumley et al, 2005 ; Parling et al, 2010 ; Igarashi et al, 2011 ; Baeza-Velasco et al, 2012 ; Baker et al, 2014 ; Lichev et al, 2014 ; Maroti et al, 2017 ). In the few studies including medical conditions (or medical controls), the results have also been mixed, with some studies showing positive associations (Baeza-Velasco et al, 2012 ; Maroti et al, 2017 ), while others do not (Consoli et al, 2009 ; Lane et al, 2015a ; Burger et al, 2016 ; Neumann et al, 2017 ).…”
