Fig. 2.
The frequency of the combined endpoint (A) and in-hospital mortality (B) in association with hs-cTnI (gray bars), and the revised cardiac index ‘Lee index’ (dark bars). Compared with patients with normal hs-cTnI on admission, patients with elevated hs-cTnI are more likely to suffer combined endpoint (P < 0·001), There is also an increasing trend in mortality of elevated hs-cTnI group (P = 0·057). The occurrence of the combined endpoint was also related to the Lee index (P < 0·001), Comparable results could be observed for in-hospital mortality (P = 0·014).
