You take care of a 67-year-old female patient in the emergency room whose reason for admission is pain in the right calf. The questioning and clinical examination reveal a progressive cancer during treatment and localized sensitivity along the deep venous network. RIGHT. the rest of the examination is unremarkable. you use a simplified clinical prediction model for deep vein thrombosis (dVT) which indicates a probability of dvt of 17%. you request a venous duplex of the lower limbs to confirm this suspicion of dvt. among Which of the following statements is (are) correct?
The post-test probability of DVT depends on the sensitivity of the venous Doppler ultrasound.
The pre-test probability of pVT depends on the specificity of the venous duplex scan.
The post-test probability of pVT depends on the likelihood ratio of venous duplex ultrasound.
The post-test probability of DVT depends on the intrinsic performance of venous Doppler ultrasound.
The post-test probability of TVP can be determined graphically using the Fagan nomogram.
