Ratio comparing outcome prevalence between two groups
A measure comparing the prevalence of a finding (e.g., T-wave inversion) between two groups, such as athletes versus non-athletes, analogous to relative risk but for cross-sectional prevalence data. A PR of 1.49 means the finding was about 49% more common in one group, though this says nothing about absolute risk if baseline prevalence is low.
