AC SRS and NAC SRS were analyzed in two separate models due to significant correlation between AC SRS and NAC SRS.
* SRS group: Classifying the severity of MPI by SRS 0–3, 4–8, 8–13, > 13.
** AC: attenuation correction; BMI: body mass index; FRS: Framingham risk score; gr: group; LVEF: left ventricular ejection fraction; NAC: non-attenuation correction; SRS: summed rest score.
