Percentage of cTnI tests with normal value and with serial cTnI tests.
Legend: Comparison of cardiac troponin I (cTnI) test results between a general university hospital (GUH) and a specialized cardiology university hospital (CUH). In the GUH, 70% of tests indicated normal cTnI levels, with 40% of the tests being serial measurements. In the CUH, only 45% of tests showed normal levels, while 53% were serial measurements. The data suggest a statistically significant difference (p < 0.0001) between the two settings, indicating a higher prevalence of elevated cTnI levels and more frequent use of serial testing in the cardiology-specialized hospital.
