Relationship between EFM exposure and cesarean delivery

Reference no: EM13953291

Consider the data taken from a study attempting to determine whether the use of electronic fetal monitoring (EFM) during labor affects the frequency of cesarean section deliveries. Of the 5824 infants included in the study, 2850 were electronically monitored and 2974 were not. The outcomes are given in Table E4.11.

TABLE E4.11
		EFM Exposure
Cesarean Delivery	Yes		No	Total
Yes	358		229	587
No	2492		2745	5237
Total	2850		2974	5824

(a) Use the data from the group without EFM exposure, calculate the 95% confidence interval for the proportion of cesarean delivery.

(b) Calculate the 95% confidence interval for the odds ratio representing the relationship between EFM exposure and cesarean delivery.
