Treating Systematic Errors in Multiple Sclerosis Data [PDF]

open access: yes, 2005
Multiple sclerosis (MS) is characterized by high variability between patients and, more importantly here, within an individual over time. This makes categorization and prognosis difficult.

Bayesian Nonlinear Models for Repeated Measurement Data: An Overview, Implementation, and Applications

open access: yesMathematics, 2022
Nonlinear mixed effects models have become a standard platform for analysis when data is in the form of continuous and repeated measurements of subjects from a population of interest, while temporal profiles of subjects commonly follow a nonlinear ...

Intra-individual reaction time variability and all-cause mortality over 17 years: A community-based cohort study [PDF]

open access: yes, 2013
Background: very few studies have examined the association between intra-individual reaction time variability and subsequent mortality. Furthermore, the ability of simple measures of variability to predict mortality has not been compared with more ...

Cellular Adhesion Molecules in Healthy Subjects: Short Term Variations and Relations to Flow Mediated Dilation

open access: yesBiomarker Insights, 2008
The objective was primarily to describe short term intra-individual variation in serum levels of soluble adhesion molecules (sCAMs: E-selectin, P-selectin, intercellular adhesion molecule-1(sICAM-1) and vascular cellular adhesion molecule-1(sVCAM-1)) in ...

Intra-individual Variation in Nineteenth-century Private Letters

open access: yes, 2021
This chapter explores intra-individual variation (IAV) in three nineteenthcentury private letters. Quantitative and qualitative analyses of these letters, written in 1845 by a maid working in Graz (Austria) to her sister in Straden (Austria), illustrate to what extent the language use of the same person can vary in writing.

Intra-individual variation in commonly analyzed serum constituents.

open access: yesClinical Chemistry, 1979
Abstract Concentrations of 27 commonly estimated serum constituents were measured in blood sampled from 20 apparently healthy volunteers at 0830, 1230, and 1630 hours on each of four days, at weekly intervals. Time-dependent statistically significant (p less than or equal to 0.01) variation was observed in 12 of the constituents.

A test-retest reliability study of human experimental models of histaminergic and non-histaminergic itch [PDF]

open access: yes, 2017
Numerous exploratory, proof-of-concept and interventional studies have used histaminergic and non-histaminergic human models of itch. However, no reliability studies for such surrogate models have been conducted.
