revision based on new information about signals
observed during the medical encounter: a symptom, a
sign, a piece of information based on the medical history, a laboratory test. Probability revision requires

A method of calculating diagnostic indexes for possible cancer symptoms in general practice
(Journal article; Tidsskriftartikkel; Peer reviewed, 1990)
Most medical encounters start with the presentation
of symptomns that lead to hypotheses about
the diagnosis. It might be useful to know the probability
of a disease when a symptom of it is presented in
a consulation with a general practitioner, i.e., the
positive predictive value (PPV) of a particular symptom
in relation to a disease. A diagnostic index of this
kind would need to be based ...
More diagnostic indexes from general practice for some important forms of cancer
(Journal article; Tidsskriftartikkel; Peer reviewed, 1990)
A method of calculating positive predictive
values (PPVs) and likelihood ralios (LRs) on the basis
of Bayesian probabilities has been described previously.
In the present article the method is applied to a sore
which does not heal in relation to skin cancer, a lump
in the breast in relation to female breast cancer, genital
bleeding in relation to internal genital cancer in
fernales and ...
