Goodness-of-fit two-phase sampling designs for time-to-event outcomes: a simulation study based on New York University Women’s Health Study for breast cancer

BMC Medical Research Methodology, 2023
Background Sub-cohort sampling designs such as a case-cohort study play a key role in studying biomarker-disease associations due to their cost effectiveness.

A robust ensemble feature selection approach to prioritize genes associated with survival outcome in high-dimensional gene expression data

Frontiers in Systems Biology
Exploring features associated with the clinical outcome of interest is a rapidly advancing area of research. However, with contemporary sequencing technologies capable of identifying over thousands of genes per sample, there is a challenge in ...

Calculation of NNTs in RCTs with time-to-event outcomes: A literature review

BMC Medical Research Methodology, 2009
Background The number needed to treat (NNT) is a well-known effect measure for reporting the results of clinical trials. In the case of time-to-event outcomes, the calculation of NNTs is more difficult than in the case of binary data.

Definition and Estimation of Covariate Effect Types in the Context of Treatment Effectiveness

Mathematics, 2020
In some clinical studies, assessing covariate effect types indicating whether a covariate is predictive and/or prognostic is of interest, in addition to the study endpoint. Recently, for a case with a binary outcome, Chiba (Clinical Trials, 2019; 16: 237–

Solid Pseudopapillary Neoplasm of the Pancreas in Children and Adolescents: Expert Recommendations

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Solid pseudopapillary neoplasm of the pancreas (SPN) is a rare low‐grade malignant exocrine pancreatic tumor, mostly discovered during the second decade of life in females, with a very good prognosis, provided microscopically complete surgical excision is achieved.

joineR: Joint modelling of repeated measurements and time-to-event data [PDF]

, 2012
The joineR package implements methods for analysing data from longitudinal studies in which the response from each subject consists of a time-sequence of repeated measurements and a possibly censored time-toevent outcome.

Time-based and event-based prospective memory in autism spectrum disorder: The roles of executive function, theory of mind, and time-estimation [PDF]

, 2012
Prospective memory (remembering to carry out an action in the future) has been studied relatively little in ASD. We explored time-based (carry out an action at a pre-specified time) and event-based (carry out an action upon the occurrence of a pre ...

Pain now or later: an outgrowth account of pain-minimization. [PDF]

PLoS ONE, 2015
The preference for immediate negative events contradicts the minimizing loss principle given that the value of a delayed negative event is discounted by the amount of time it is delayed.
