Diagnostic and ICP related characteristics of included children.

	Child A	Child B	Child C
Childs age at time of diagnosis	Postnatal 6–10 years	Pre- or perinatal	Postnatal 0–5 years
Diagnosis	DQ070	DQ038	DQ038B
	DG950B		DG910
	DR519		DR519
Mental disability	None	None	None
Childs age at time of first ICP lowering treatment	8 years	2 months	3 years
Surgical ICP lowering treatment 1 year prior to implantation of telemetric ICP sensor	Occipitocervical decompression ×2, postoperative CSF leak, treated with lumbar drain	None, one adjustment of valve settings of initial VP shunt	Initial VP shunt implantation, one shunt revision
Reason for implantation	Satisfactory postoperative imaging after the second operation.	Adjustable VP shunt.	Fixed VP shunt.
	Five months post surgery continuous complaints of posture related headache, CTc without hydrocephalus.	Episodic symptoms where the child needs to lay down for 2–3 days, accompanied by explosive vomiting.	CTc could indicate overdrainage.
	Implantation to evaluate ICP.	Diagnostic evaluation for epilepsy, unknown if the seizures are ICP related.	Both good and bad days. Active and well on good days; preferred to sleep/lay down on bad days.
		CTc without hydrocephalus.	Implantation of a telemetric ICP sensor and an adjustable VP shunt, to evaluate if the symptoms were ICP related and to assess future valve settings.
		Implantation to evaluate ICP during episodic symptoms/seizures.
Age at time of first telemetric ICP sensor	9 years	3 years	3 years
