Fig. (2) Females/males odds ratio (OR) plot for each type of ACHD. Each point in the graph represents an OR, while the error bars correspond to its 95% confidence intervals (95% CI). An OR with 95% CI>1.0 indicates significantly higher likelihood for females, whereas an OR with 95% CI <1.0 indicates significantly higher likelihood for males. Atrial septal defect was more common in females. Pulmonary valve stenosis was more common in males. Abbreviations: ASD: Atrial septal defect, COA: coarctation of aorta, Fallot: Fallot’s tetralogy OR: odds ratio, PAPVR: Partial anomalous pulmonary venous return, PDA: Patent ductus arteriosus, PS: Pulmonary valve stenosis, VSD: Ventricular septal defect.
