2. Figure 1
Flow chart of the recruitment and selection process, with biomarker results on admission and adjudicated final diagnoses. The asterisk (*) indicates that in the subgroup of patients with non-ST-segment elevation myocardial infarction presenting with a discordant ultra-sensitive copeptin+/medium-sensitivity cardiac troponin I− pattern on admission, a third high-sensitivity cardiac troponin I sample at >6 hours was required to confirm the diagnosis of non-ST-segment elevation myocardial infarction in 3 patients. Cop-cTnI = copeptin cardiac troponin I; NCCP = noncoronary chest pain; NSTEMI = with non-ST-segment elevation myocardial infarction.

3. Figure 2
Box-whisker graphs of ultra-sensitive copeptin levels in the groups with noncoronary chest pain and non–ST-segment elevation myocardial infarction. Box-whisker plots show the 25th and 75th percentile ranges (box) with 95% confidence intervals (whiskers) and median values (transverse lines in the box). Statistically significant differences were found between the 2 groups (P < .001, Mann–Whitney U test). NCCP = noncoronary chest pain; NSTEMI = non-ST-elevation myocardial infarction.
