Qualitative assessment of overall evidence for Doppler velocimetry and fetal movement monitoring according to CHERG rules

	Quality Assessment					Summary of findings
				Generalizability		Number of events		Pooled Effect
No. of studies	Design	Limitations	Consistency	Generalizability to Population of Interest	Generalizability to intervention of Interest	Intervention	control	RR ( 95 % CI)
Effect of surveillance of high risk pregnancies with Doppler velocimetry: Outcome perinatal mortality: Grade quality of evidence ‘Moderate’
16	RCT	Methods of sequence generation and allocation concealment were not adequate in most of the studies	No heterogeneity (I2=0%)	All the studies from developed countries except one which is from South Africa	Doppler velocimetry of umbilical and fetal arteries for surveillance of high risk pregnancy	63	90	0.71 (0.52-0.98)
Effect of surveillance of high risk pregnancies with Doppler velocimetry: Outcome stillbirth: Grade quality of evidence ‘Low’
15	RCT	Methods of sequence generation and allocation concealment were not adequate in most of the studies	No heterogeneity (I2=0%)	All the studies from developed countries except one which is from South Africa	Doppler velocimetry of umbilical and fetal arteries for surveillance of high risk pregnancy	27	43	0.65 (0.41-1.04)
Effect of fetal movement monitoring on stillbirths: Grade quality of evidence “very low”
14	RCT, quasi experimental and observational studies	Most of the evidence from observation studies. Of the four RCTs, only one compared fetal movement monitoring versus no fetal movement monitoring. This RCT showed no effect of fetal movement monitoring on stillbirths	Data not pooled due to gross clinical heterogeneity	Most of the studies from developed countries	No consensus on single counting method. Cardif method (Count to ten) was the most widely used method	Data not pooled
