Univariable and multivariable linear regression analyses investigating the effect of baseline characteristics on the left ventricular ejection fraction (LVEF (%)), left ventricular end-diastolic volume (LVEDV (mL)) at 4-month follow-up. CTO, coronary chronic total occlusion; GOODCOLL, well -developed collaterals to the CTO; pPCI, primary percutaneous coronary intervention.
