  1. The number of participants in each study was included; however, it was not possible to calculate the total number of participants across studies due to a high likelihood of duplicate studies (since many studies used similar databases). In the majority of studies, an age range of the study participants was specified; study populations ranging between 18 and > 85 years old were included in this review. Female gender formed the majority of participants across most study groups. N/R not reported; AMI acute myocardial infarction
