Description

midas fagan displays a Fagan nomogram showing how the pre-test

positive and negative likelihood ratios from the bivariate meta-analysis.
Up to three pre-test probabilities may be specified simultaneously.

pretestprob(numlist) one to three pre-test probabilities
(proportions between 0 and 1). Required.

lrplus(#) override the summary LR+ from the model.

lrminus(#) override the summary LR- from the model.

usemodel forces use of the model LR estimates even if overrides are supplied.
