Blood pressure variability and cardiovascular risk in the PROspective study of pravastatin in the elderly at risk (PROSPER) [PDF]

open access: yes, 2012
Variability in blood pressure predicts cardiovascular disease in young- and middle-aged subjects, but relevant data for older individuals are sparse. We analysed data from the PROspective Study of Pravastatin in the Elderly at Risk (PROSPER) study of ...

Confidence interval how sure you are?

open access: yesJournal of Applied Hematology, 2014
Previously, researchers were reported P value as a basis for conclusion, but in this era of evidence-based medicine we are interested now about the precision of the results obtained that allow us to make right decisions in health care practice.

On construction of the smallest one-sided confidence interval for the difference of two proportions [PDF]

open access: yes, 2010
For any class of one-sided $1-\alpha$ confidence intervals with a certain monotonicity ordering on the random confidence limit, the smallest interval, in the sense of the set inclusion for the difference of two proportions of two independent binomial ...

A New Exact Confidence Interval for the Difference of Two Binomial Proportions

open access: yesRevstat Statistical Journal, 2020
We consider interval estimation of the difference between two binomial proportions. Several methds of constructing such an interval are known. Unfortunately those confidence intervals have poor coverage probability: it is significantly smaller than the ...

Prognostic value of the myocardial salvage index measured by T2-weighted and T1-weighted late gadolinium enhancement magnetic resonance imaging after ST-segment elevation myocardial infarction: A systematic review and meta-regression analysis [PDF]

open access: yes, 2020
In all patients with ST-segment elevation myocardial infarction, risk stratification should be performed before discharge. The measurement of therapy efficiency with magnetic resonance imaging has been proposed as part of the risk assessment, but it has ...

Estimation of Gini Index within Pre-Specied Error Bound [PDF]

open access: yes, 2015
Gini index is a widely used measure of economic inequality. This article develops a general theory for constructing a confidence interval for Gini index with a specified confidence coefficient and a specified width.

Interval-Valued Intuitionistic Fuzzy Confidence Intervals

open access: yesJournal of Intelligent Systems, 2019
Confidence intervals are useful tools for statistical decision-making purposes. In case of incomplete and vague data, fuzzy confidence intervals can be used for decision making under uncertainty.

The Shortest Clopper–Pearson Randomized Confidence Interval for Binomial Probability

open access: yesRevstat Statistical Journal, 2017
Zieli´nski (2010) showed the existence of the shortest Clopper–Pearson confidence interval for binomial probability. The method of obtaining such an interval was presented as well. Unfortunately, the confidence interval obtained has one disadvantage: it

Confidence interval methods for antimicrobial resistance surveillance data

open access: yesAntimicrobial Resistance and Infection Control, 2021
Background Antimicrobial resistance (AMR) is one of the greatest global health challenges today, but burden assessment is hindered by uncertainty of AMR prevalence estimates.

Fletcher-Turek Model Averaged Profile Likelihood Confidence Intervals [PDF]

open access: yes, 2014
We evaluate the model averaged profile likelihood confidence intervals proposed by Fletcher and Turek (2011) in a simple situation in which there are two linear regression models over which we average. We obtain exact expressions for the coverage and the
