Reply: Admission cardiotocography: Practice based on evidence or assumptions and untested theories?

摘要

I thank Pelle Lindqvist for his interest in my commentary (1). The commentary (2) evaluated admission cardiotocography (CTG) from the perspective of clinical epidemiology - this is a part of evidence-based medicine. Lindqvist refers to his own experience, assumptions and untested theories indicating that admission CTG in all women improves outcomes in high-risk pregnancies. It is well known that it is difficult to draw conclusions from experiences on serious outcomes with very low frequencies. The subjective risk estimation is usually much higher than the objective (or epidemiological) risk estimation (3).
