A joint meta-analysis framework for the accuracy of two diagnostic tests accounting for varying study designs
Vera Hudak, Nicky J. Welton, Efthymia Derezea +1
Meta-analyses of the accuracy of two diagnostic tests typically assume tests are independent conditional on true disease status. This assumption is often unrealistic and violation…
Meta-analysis of networks of diagnostic tests with binary and continuous results
Efthymia Derezea, Gabriel Rogers, Nicky J Welton +1
Network meta-analysis of diagnostic test accuracy (NMA-DTA) is a relatively new field, involving combining evidence across studies to evaluate and compare the accuracy of different…
Meta-analysis of diagnostic test accuracy with multiple disease stages: combining stage-specific and merged-stage data
Efthymia Derezea, Nicky J Welton, Gabriel Rogers +1
For many conditions, it is of clinical importance to know not just the ability of a test to distinguish between those with and without the disease, but also the sensitivity to dete…
Ordinal regression for meta-analysis of test accuracy: a flexible approach for utilising all threshold data
Enzo Cerullo, Klaus Linde, Haley E. Jones +4
Standard (network) meta-analysis methods for medical test accuracy evaluation analyse the data separately for each test threshold - wasting data - unless every study reports all th…
An application of Saddlepoint Approximation for period detection of stellar light observations
Efthymia Derezea, Alfred Kume, Dirk Froebrich
One of the main features of interest in analysing the light curves of stars is the underlying periodic behaviour. The corresponding observations are a complex type of time series w…
A survey for variable young stars with small telescopes: IV -- Rotation Periods of YSOs in IC5070
Dirk Froebrich, Efthymia Derezea, Aleks Scholz +50
Studying rotational variability of young stars is enabling us to investigate a multitude of properties of young star-disk systems. We utilise high cadence, multi-wavelength optical…
