A retrospective study of patient records at Mulago Hospital in Kampala, Uganda, demonstrated the value of the curve of labor graph as a practical screening method to detect obstetric patients developing protracted labor. Time of delivery for each patient was estimated from the first measurement of cervical dilatation obtained during the active phase of labor. Labor prolonged two or more hours beyond this estimate resulted in a high incidence of operative deliveries and endometritis. and had a detrimental effect on the status of the newborn.
