Multiple comparisons: comparing more than two treatments

Comparing More Than Two Groups

Comparing Two Treatments with Multiple Competing Risks Endpoints

The problem of testing for differences between two treatments with respect to multiple competing risk time-to-event endpoints is considered. Using a nonparametric approach, a multivariate two-sample statistic is proposed for simultaneous testing for differences in cumulative incidence of the multiple competing survival endpoints. Establishment of the statistical properties of the test requires ...

Erbium-YAG laser therapy – analysis of more than 1,200 treatments

Background: Ablative laser treatment is widely used in dermatology. Different laser types are available. In contrast to that, the medical publication on erbium-YAG laser in dermatology often include small samples only. Objective: We want to demonstrate the versatility of classical erbium-YAG laser for medical conditions in dermatology in a single-center study. Materials and methods: This is a r...

Clustering More than Two Million Biomedical Publications: Comparing the Accuracies of Nine Text-Based Similarity Approaches

BACKGROUND We investigate the accuracy of different similarity approaches for clustering over two million biomedical documents. Clustering large sets of text documents is important for a variety of information needs and applications such as collection management and navigation, summary and analysis. The few comparisons of clustering results from different similarity approaches have focused on s...
