Identifying early-measured variables associated with APACHE IVa providing incorrect in-hospital mortality predictions for critical care patients

Scientific Reports, 2021
APACHE IVa provides typically useful and accurate predictions on in-hospital mortality and length of stay for patients in critical care. However, there are factors which may preclude APACHE IVa from reaching its ceiling of predictive accuracy.

A Simulation-Based Testing of Difference in the Means of Gamma-Distributed Positive Quantities

Applied Sciences, 2023
This paper presents a simulation-based testing procedure that can be easily applied by practitioners who try to determine whether two gamma-distributed variables have the same expected values. From both theoretical and practical points of view, the gamma

Inclusion of non-inferiority analysis in superiority-based clinical trials with single-arm, two-stage Simon's design

Contemporary Clinical Trials Communications, 2020
Introduction: Non-inferiority (NI) analysis is not usually considered in the early phases of clinical development. In some negative phase II trials, a post-hoc NI analysis justified additional phase III trials that were successful.

Quantitative Analysis of the Balance Property in Factorial Experimental Designs 2⁴ to 2⁸

Mathematics, 2022
Experimental designs are built by using orthogonal balanced matrices. Balance is a desirable property that allows for the correct estimation of factorial effects and prevents the identity column from aliasing with factorial effects.
