However, TR ratings and investments were highly correlated in both conditions (mean linear correlation coefficient r = 0.65 in EC and 0.61 in CC, corresponding to P -values smaller than 10 −8 in both cases) and correlations were also highly significant between TR ratings and ERs (mean r = 0.72 in EC, 0.69 in CC, P < 10 −9 ).
