Evaluation of Randomised Controlled Trials Published in Indian Specialty Dental Journals for Statistical Testing of Baseline Differences: A Meta-Epidemiological Study

Indian Journal of Dental Research, 2023
Background: In randomised controlled trials (RCTs), the application of a test of significance to compare the baseline differences between the intervention groups is a common practice, though it has been condemned by many researchers.

Study designs: Part 5 – interventional studies (II)

Perspectives in Clinical Research, 2019
In the fifth piece of this series on research study designs, we continue the discussion on interventional studies (clinical trials), in which the investigator decides whether or not a particular participant receives the exposure (or intervention).

Optimal Resource Allocation in Random Networks with Transportation Bandwidths [PDF]

, 2009
We apply statistical physics to study the task of resource allocation in random sparse networks with limited bandwidths for the transportation of resources along the links. Useful algorithms are obtained from recursive relations.

Comparison of sampling effort allocation strategies in a stratified random survey with multiple objectives

Aquaculture and Fisheries, 2020
Stratified random survey is commonly used to estimate abundance indices of fish populations in multispecies survey, providing reliable data for stock assessment and fisheries management. In some cases, however, the sample size is relatively small because
