Quartile Distribution of Initial, Maximum, and Change in Troponin Level

Troponin Leveln25th PercentileMedian (range)75th Percentile
Initial troponin22,384a0.010.02 (0-360.92)0.07
Maximum troponin23,9650.010.03 (0-647.54)0.10
Change in troponin (maximum – minimum)23,9650.000.00 (0-647.54)0.03
  • aIn our analysis, an initial troponin value that was below detectable limit was considered missing; hence, the n is 1,581 less than the sample size for the maximum troponin and change in troponin.
