Foundational Statistical Principles in Medical Research: Sensitivity, Specificity, Positive Predictive Value, and Negative Predictive Value

Medicina, 2021
Sensitivity, which denotes the proportion of subjects correctly given a positive assignment out of all subjects who are actually positive for the outcome, indicates how well a test can classify subjects who truly have the outcome of interest. Specificity,

Coexistence of critical sensitivity and subcritical specificity can yield optimal population coding

, 2017
The vicinity of phase transitions selectively amplifies weak stimuli, yielding optimal sensitivity to distinguish external input. Along with this enhanced sensitivity, enhanced levels of fluctuations at criticality reduce the specificity of the response.

Factors Associated with Marburg Hemorrhagic Fever: [PDF]

, 2010
Background. Reliable on-site polymerase chain reaction (PCR) testing for Marburg hemorrhagic fever (MHF) is not always available. Therefore, clinicians triage patients on the basis of presenting symptoms and contact history.

Effects of chronic browsing on life‐history traits of an irruptive large herbivore population

Population Ecology, EarlyView.
This study aimed to determine the relationship between diet quality, body mass, and size (hind foot length), and female reproduction and sought to identify the mechanism by which high density under severe food limitations is maintained. Our results demonstrated that sika deer introduced to Nakanoshima Island have maintained high densities through high ...

Evaluation of updated sepsis scoring systems and systemic inflammatory response syndrome criteria and their association with sepsis in equine neonates [PDF]

, 2018
BackgroundThe original equine sepsis score provided a method of identifying foals with sepsis. New variables associated with sepsis have been evaluated, but the sepsis score has not been updated.ObjectivesTo evaluate the sensitivity and specificity of 2 ...

Combining transient dynamics and logistic‐asymptotic growth to study the recovery of two seabird populations after rat eradication

Population Ecology, EarlyView.
This study examines the demographic dynamics of two seabird populations on Tromelin Island, 15 years after the eradication of brown rats. The results indicate that these populations are in good health and are expected to continue growing until breeding sites are saturated in about a century.

Measurements of complement factor H-related protein (BTA-TRAK (TM) assay) and nuclear matrix protein (NMP22 assay) - Useful diagnostic tools in the diagnosis of urinary bladder cancer? [PDF]

, 2003
Between 1997 and 2000 we investigated in a prospective study the voided urine samples of all consecutive patients undergoing cystoscopy independent from their clinical background (n=705) with the BTA-TRAK(TM) assay (Bard Diagnostics, Redmont, USA ...

Sensitivity and Specificity of Photoaptamer Probes [PDF]

Molecular & Cellular Proteomics, 2003
The potential of photoaptamers as proteomic probes was investigated. Photoaptamers are defined as aptamers that bear photocross-linking functionality, in this report, 5-bromo-2'-deoxyuridine. A key question regarding the use of photoaptamer probes is the specificity of the cross-linking reaction.

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada

Population Ecology, EarlyView.
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Diagnostic Value of Lactoferrin in Diagnosis of Urinary Tract Infections in Children

مجله دانشکده پزشکی اصفهان, 2018
Background: Urinary tract infections is a common disease, especially in children, and is diagnosed through urine culture. The aim of this study was to evaluate the diagnostic value of lactoferrin in the diagnosis of urinary tract infections. Methods: In
