Association of CRI with high blood level of troponin among AMI patients by study seasons (Table 4):
Overall, the results demonstrate that there were no significant associations between recent CRI and high blood levels of troponin among patients with AMI, during different study seasons. However, there was a positive trend in the association between CRI and high-troponin AMI, especially during the 2018 influenza season where the unadjusted RR is 1.26 and the adjusted RR is 1.79. However, these estimates were not statistically significant. Similarly, during all influenza seasons, there was a slight positive trend in the unadjusted RR of 1.28 and the adjusted RR of 1.12, but again, the results were not statistically significant.
