Diagnostic test accuracy: application and practice using R software

Studies of diagnostic test accuracy

Definition of a diagnostic test accuracy study? o A diagnostic test accuracy study evaluates the accuracy of index test in correctly distinguishing between those with disease and those without disease compared to gold standard test. o Gold standard test is also called criterion test or reference test. o For a diagnostic test to be accurate, it should be both valid (accuracy) and reliable (preci...

Cochrane diagnostic test accuracy reviews

In 1996, shortly after the founding of The Cochrane Collaboration, leading figures in test evaluation research established a Methods Group to focus on the relatively new and rapidly evolving methods for the systematic review of studies of diagnostic tests. Seven years later, the Collaboration decided it was time to develop a publication format and methodology for Diagnostic Test Accuracy (DTA) ...

Identifying Diagnostic Test Accuracy Publications using a Deep Model

In this work, we used a deep model architecture to identify DTA studies pertaining to a given review topic. We were provided the list of relevant documents selected based on abstracts and full text for different reviews topics. We extracted the abstract and title to be used as features to describe those documents, and learned the deep neural net model that takes as input the abstract and title ...
