Abbreviations: CABG, coronary artery bypass graft; CI, confidence interval; HR, hazards ratio; PTCA, percutaneous transluminal coronary angioplasty.
a
Hazard ratios represent the ratio of screening vs no-screening participants from unadjusted Cox proportional hazards regression analysis.
b
Log-rank P values are derived from unadjusted actuarial survival analysis.
c
One patient had 2 secondary events.
d
Three patients underwent both PTCA and CABG surgery.
