Estimating the Individual Treatment Effect on Survival Time Based on Prior Knowledge and Counterfactual Prediction

open access: yesEntropy, 2022
The estimation of the Individual Treatment Effect (ITE) on survival time is an important research topic in clinics-based causal inference. Various representation learning methods have been proposed to deal with its three key problems, i.e., reducing ...

How to use χ2 test correctly——the three kinds of special tests of the survival data and the implementation of the SAS software

open access: yesSichuan jingshen weisheng, 2021
The purpose of the paper was to introduce the three special tests of the survival data and the SAS implementation. Specifically, it was the multiple comparisons, the trend test and the covariate test of the survival data.

Simulating time-to-event data under the Cox proportional hazards model: assessing the performance of the non-parametric Flexible Hazards Method

open access: yesFrontiers in Applied Mathematics and Statistics, 2023
Numerous methods and approaches have been developed for generating time-to-event data from the Cox Proportional Hazards (CPH) model; however, they often require specification of a parametric distribution for the baseline hazard even though the CPH model ...

High-Dimensional Mediation Analysis Based on Additive Hazards Model for Survival Data

open access: yesFrontiers in Genetics, 2021
Mediation analysis has been extensively used to identify potential pathways between exposure and outcome. However, the analytical methods of high-dimensional mediation analysis for survival data are still yet to be promoted, especially for non-Cox model ...

What Do the First 597 Global Fungal Red List Assessments Tell Us about the Threat Status of Fungi?

open access: yesDiversity, 2022
Fungal species are not immune to the threats facing animals and plants and are thus also prone to extinction. Yet, until 2015, fungi were nearly absent on the IUCN Red List.

Benchmarking survival outcomes: A funnel plot for survival data [PDF]

open access: yesStatistical Methods in Medical Research, 2022
Benchmarking is commonly used in many healthcare settings to monitor clinical performance, with the aim of increasing cost-effectiveness and safe care of patients. The funnel plot is a popular tool in visualizing the performance of a healthcare center in relation to other centers and to a target, taking into account statistical uncertainty.

Modeling left-truncated and right-censored survival data with longitudinal covariates [PDF]

open access: yes, 2012
There is a surge in medical follow-up studies that include longitudinal covariates in the modeling of survival data. So far, the focus has been largely on right-censored survival data.

%JM: A SAS Macro to Fit Jointly Generalized Mixed Models for Longitudinal Data and Time-to-Event Responses

open access: yesJournal of Statistical Software, 2018
In clinical research subjects are usually observed during a period of time. Primary and secondary endpoints are often either responses measured longitudinally over time or the time at which an event of interest occurs.
