SURVIVAL ANALYSIS APPLIED TO COMMERCIAL BANK IN VENEZUELA BETWEEN 1996 AND 2004 ANÁLISIS DE SUPERVIVENCIA APLICADO A LA BANCA COMERCIAL VENEZOLANA, 1996 – 2004

Revista Colombiana de Estadística, 2007
In this work, survival analysis is used as a statistical technique to find out when any bank probably changes of state. The random variable to study is the observed time period of the lifetime where there is a change of state. Special interest is focused

Description of survival data extended to the case of competing risks: a teaching approach based on frequency tables

Epidemiology, Biostatistics and Public Health, 2022
Survival analysis is a powerful statistical tool to study failure-time data. In introductory courses students learn how to describe right-censored survival time data using the product-limit estimator of the survival function on a given end-point relying

A Low Psoas Muscle Index Was Associated With a Poorer Overall Survival in Patients Who Underwent Percutaneous Nephrostomy

Aging and Cancer, EarlyView.
In patients with malignant ureteral obstruction undergoing percutaneous nephrostomy, sarcopenia defined by a low psoas muscle index was independently associated with poor overall survival on multivariate Cox regression analysis, suggesting that preoperative assessment of psoas muscle index may aid prognostic stratification in this population.

Ofatumumab in Myelin Oligodendrocyte Glycoprotein Antibody–Associated Disease: A Comparison With Rituximab

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To evaluate the efficacy and safety of ofatumumab in patients with myelin oligodendrocyte glycoprotein antibody–associated disease (MOGAD), and compare it with rituximab. Methods We conducted a single–center, observational study including 22 MOGAD patients treated with ofatumumab and 21 treated with rituximab.

survivalBIV : Estimation of the Bivariate Distribution Function for Sequentially Ordered Events Under Univariate Censoring

Journal of Statistical Software, 2012
In many medical studies, patients can experience several events. The times between consecutive events (gap times) are often of interest and lead to problems that have received much attention recently.

Risk of Non‐Arteritic Anterior Ischemic Optic Neuropathy in Idiopathic Intracranial Hypertension Patients Treated with GLP‐1 Receptor Agonists

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction Glucagon‐like peptide‐1 receptor agonists (GLP‐1 RAs) have demonstrated significant weight‐reducing effects and may offer benefits in idiopathic intracranial hypertension (IIH); however, recent concerns about the risk of non‐arteritic anterior ischemic optic neuropathy (NAION) have emerged.

Comparative Effectiveness and Safety of Inebilizumab Versus Rituximab in AQP4‐IgG‐Positive NMOSD

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Rituximab (anti‐CD20, RTX) and inebilizumab (anti‐CD19, INE) represent B‐cell‐depleting therapies used for aquaporin‐4 antibody‐positive (AQP4‐IgG+) neuromyelitis optica spectrum disorder (NMOSD); however, direct comparative evidence remains limited.

Strong representation of the Kaplan–Meier and hazard estimators for censored data with m-widely acceptable dependence

Statistical Theory and Related Fields
This paper investigates the asymptotic properties of the Kaplan–Meier and hazard estimators for censored survival time data. We conduct this analysis under the assumption of m-widely acceptable (m-WA) dependence, a generalized form of weak correlation ...

Modified Weighted Kaplan-Meier Estimator

Pakistan Journal of Statistics and Operation Research, 2007
En muchos estudios médicos, la mayoría de los sujetos del estudio no llegan al evento de interés durante el período de estudio. En tales situaciones, el estimador de Kaplan Meier puede estimar las probabilidades de supervivencia para la observación censurada.
