Data are presented as n (%).
30-day peak hs-cTn I was available in 4086/7958 (51.3%) in LOD and 2529/4457 (56.7%) in mild elevation groups of the entire population.
30-day peak hs-cTn I was available in 2142/3869 (55.4%) in LOD and 2211/3869 (57.1%) in mild elevation groups of the propensity score matched population.
