Describing randomization in trials included in systematic reviews in orthopaedic surgery
Bone & Joint OpenAims: Systematic reviews of randomized controlled trials (RCTs) are the highest level of evidence used to inform patient care. However, it has been suggested that the quality of randomization in RCTs in orthopaedic surgery may be low. This study aims to

On the Uniqueness of Wald Sequential Tests
The Annals of Mathematical Statistics, 1956 Under certain mild restrictions on the distributions involved, it is shown that the probabilities of the two types of error uniquely determine the two bounds characterizing the Wald sequential probability ratio test.

One statistical test is sufficient for assessing new predictive markers
BMC Medical Research Methodology, 2011 Background We have observed that the area under the receiver operating characteristic curve (AUC) is increasingly being used to evaluate whether a novel predictor should be incorporated in a multivariable model to predict risk of disease.
