AC SSS and NAC SSS were analyzed in two separate models due to significant correlation between AC SSS and NAC SSS.
* SSS group: classifying the severity of MPI by SSS 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; SSS: summed stress score.
