MAGNETIC RESONANCE IMAGING TEST (MRI) for evaluation of lymph node metastasis in women with invasive cervical cancer

Description

This dataset gives the observed cross-tabulation of the MRI (test under evaluation) and histologic/cytologic specimens obtained by surgery or lymph node biopsy (reference test).

Usage

data(MRI)

Format

A matrix with 10 observations on the following 4 variables.

++

Observed individuals who tested positive on both tests

+-

Observed individuals who tested positive on the test under evaluation and negative on the reference test

-+

Observed individuals who tested negative on the test under evaluation and positive on the reference test

---

Observed individuals who tested negative on both tests
