For instance, we may be interested in determining if a new diagnostic test is noninferior to the standard reference test because the new test might be inexpensive to the extent that some small inferior margi...

The specificity and sensitivity of a quantitative diagnostic test depends on the chosen cutoff point. The common practice of selecting a cutoff point that maximizes the specificity plus the sensitivity, as judged from the observed test results, is studied here by simulation. Test performance is on average assessed too optimistically by this procedure--a phenomenon of importance when sample size...

OBJECTIVES To investigate whether plain radiographs can show changes in joint damage due to rheumatoid arthritis (RA) within 3 months. METHODS 188 film pairs taken with a 3 month interval were evaluated. They were scored with (chronological) and without (paired) knowledge of the sequence of the films according to the Sharp/van der Heijde method. Changes in joint damage were analysed on a grou...

OBJECTIVES The study systematically compared different measures of ST segment depression from the treadmill exercise test. BACKGROUND The value of the treadmill exercise test for objectively measuring treatment effects is limited by random error in the measurement of ST depression and may be biased by regression to the mean or by the decision to terminate the test. METHODS Treadmill exercis...
