Table 4 Verification: List of children whose defects didn’t spontaneously close

ID	Predicted probability	Actual outcome	Birth weight(kg)	Defect diameter(mm)	Note
01	0.8469	Thoracotomy surgery	2	3.8
02	0.6264	Mortality	2.5	3.2	Respiratory failure
03	0.3467	Mortality	2.55	2.4	Down’s syndrome
04	0.4700	Defect reduced	3	3
05	0.5496	Defect persisted	4.5	4
06	0.7362	Defect persisted	3.15	3.9
07	0.4056	Defect reduced	3.95	3.3
08	0.7984	Defect persisted	3.05	4.1

In the binary logistic regression, spontaneous closure is defined as 0, persisted defect is defined as 1, and predicted probability stands for the possibility of persisted defects
Patients with predicted possibility above 0.5 experienced surgery (No.01), mortality (No.02), or persistent defects (No.05,06.08), while patients with predicted possibility below 0.5 had reduced defects (No.04,07). Patient No.03 has Down’s syndrome
