Differences in left ventricular ejection fraction (LVEF) on cardiac magnetic resonance (CMR) following the administration of ferric carboxymaltose in patients with right ventricular systolic dysfunction at enrolment. All models were adjusted by hospital (as a cluster variable), the interaction term treatment × visit (7 and 30 days), age, gender, and the baseline (pretreatment) value of the regressed outcome. RVEF, right ventricular ejection fraction.
