Medical therapy, radiofrequency ablation or cryoballoon ablation as first-line treatment for paroxysmal atrial fibrillation: interpreting efficacy through restricted mean survival time and network meta-analysis [PDF]

open access: yesReviews in Cardiovascular Medicine, 2021
When multiple treatments are available, network meta-analysis can evaluate data to rank the relative effectiveness. We applied this approach to first-line treatments for paroxysmal atrial fibrillation (medical therapy, radiofrequency ablation or ...

A Brief Overview of Restricted Mean Survival Time Estimators and Associated Variances

open access: yesStats, 2020
Restricted Mean Survival Time ( R M S T ) experiences a renaissance and is advocated as a model-free, easy to interpret alternative to proportional hazards regression and hazard rates with implication in causal inference. Estimation of R M S T

Matched design for marginal causal effect on restricted mean survival time in observational studies

open access: yesJournal of Causal Inference, 2023
Investigating the causal relationship between exposure and time-to-event outcome is an important topic in biomedical research. Previous literature has discussed the potential issues of using hazard ratio (HR) as the marginal causal effect measure due to ...

Early combination of albumin with crystalloids administration might be beneficial for the survival of septic patients: a retrospective analysis from MIMIC-IV database

open access: yesAnnals of Intensive Care, 2021
Background Fluid therapy is a cornerstone in the treatment of sepsis. Recently, the guidelines have recommended the combined administration that using crystalloids plus albumin for septic patients, but the optimal timing for albumin combined is still ...

Generalized fiducial inference for the restricted mean survival time

open access: yes, 2023
The standard modeling approach for time-to-event outcomes subject to censoring is based on the hazard function, with hazard ratios capturing the effect of exposures on the risk of outcome.

Consideration of Surrogate Endpoints for Overall Survival Associated With First-Line Immunotherapy in Extensive-Stage Small Cell Lung Cancer

open access: yesFrontiers in Oncology, 2021
BackgroundThe combination of immune checkpoint inhibitors (ICIs) and chemotherapy is known to improve overall survival (OS) in patients with extensive-stage small cell lung cancer (ES-SCLC).

Methods for Direct Modeling of Restricted Mean Survival Time for General Censoring Mechanisms and Causal Inference [PDF]

open access: yes, 2017
Restricted mean survival time (RMST) is often of great clinical interest in practice. Several existing methods involve explicitly projecting out patient-specific survival curves using parameters estimated through Cox regression. It is often be preferable

Adjusted empirical likelihood analysis of restricted mean survival time for length-biased data [PDF]

open access: yesJournal of Mahani Mathematical Research
The Restricted Mean Survival Time (RMST) serves as a valuable and extensively utilized metric in clinical trials. However, its application becomes intricate when dealing with data affected by length-biased sampling, rendering traditional inference ...

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

open access: yesMathematics, 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–
