  5. New Data in MedCalc

    It would be useful to include some tables with the normal range of variables that are looked for from time to time.
    I am thinking on heart measures by ecocardiography (left atrium diameter, thickness of left ventricule free wall or interventricular septum, ...), or hemodinamic variables: cardiac index, index of vascular resistances ...
    Thank you

  10. clavicle

    Robinson Risk Score for calculation of nonunion risk for displaced midshaft clavicle fractures. Needs 3 inputs:

    1. Smoker (yes/no)
    2. Comminution - i.e. presence of 3 or more fracture fragments (yes/no)
    3. Absolute displacement (mm)

    Logit(p) = -5.616 + (1.324 x [1 if smoker or 0 if nonsmoker]) + (0.561 x [1 if comminuted fracture or 0 if noncomminuted fracture]) + (0.153 x
    absolute fracture displacement in millimeters).

    Percentage probability of nonunion = exp(logit[p])/(1 + exp[logit(p)]) x 100.
