Results are expressed as Spearman rank correlation or Lin concordance coefficients and (95% confidence intervals). For Spearman correlation coefficients, 95% confidence intervals were bootstrapped and bias-corrected values are presented. Spearman correlation indicates the association between values, while Lin concordance coefficient evaluates the degree to which pairs of observations fall on the Y0X (i.e. the 45° line). All coefficients are statistically significant at p < 0.001.
