Correlation between plasma levels of Sdc-1 (or sTM) and each of the routine laboratory parameters. Spearman correlation coefficients and statistical analyses were determined between plasma levels of Sdc-1 or sTM and serum levels of troponin (A-B), LDH (C-D), and creatinine (E-F). Values of P < .05 and P < .01 are considered to be statistically significant and highly significant, respectively.
