Abstract:
Admission cardiotocography (CTG) was introduced as a screening test for fetal distress in labor in the late 1980s. No systematic assessments of the test were performed before it was taken into widespread use. A screening test is meant to identify individuals with an increased risk for a disease or condition before symptoms occur, to prevent and reduce morbidity or mortality. A screening test should be evaluated according to its effectiveness, prognostic values and reliability. A careful review of the research literature states that routine use of the admission CTG in low-risk women increases the incidence of minor obstetric interventions, may increase the incidence of cesarean sections, but has no impact on other important outcomes. The prognostic values are poor, and the reliability varies from good to poor. There is no evidence showing that the admission CTG is beneficial, and the test should not be offered to low-risk women.

Multiple Comparison Tests
It would be easy to compare two samples using a significance alpha level of 0.05. In other words, there is only one sample pair to be compared. However, it would be difficult to identify a significantly different sample if the number...

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
