Quartile Distribution of Initial, Maximum, and Change in Troponin Level
| Troponin Level | n | 25th Percentile | Median (range) | 75th Percentile |
|---|---|---|---|---|
| Initial troponin | 22,384a | 0.01 | 0.02 (0-360.92) | 0.07 |
| Maximum troponin | 23,965 | 0.01 | 0.03 (0-647.54) | 0.10 |
| Change in troponin (maximum – minimum) | 23,965 | 0.00 | 0.00 (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.
