Design and analysis of trials with a partially nested design and a binary outcome measure
Where treatments are administered to groups of patients or delivered by therapists, outcomes for patients in the same group or treated by the same therapist may be more similar, leading to clustering. Trials of such treatments should take account of this effect. Where such a treatment is compared with an un-clustered treatment, the trial has a partially nested design. This paper compares statis...
متن کاملClinical Trials Study Design
Observational Studies: Observational studies provide a mechanism for clarifying the epidemiology and risk factors/exposures that place populations at risk for disease. Observational studies assist in identifying clinical outcomes that might aid in predicting future disease. This type of study allows researchers to draw conclusions about responses to variables; they allow for associations but no...
متن کاملLevel Of Natriuretic Peptide Determines Outcome In Atrial Fibrillation.
Background: Natriuretic peptide (NP) is high in atrial fibrillation (AF) and may decrease after cardioversion to sinus rhythm and the levels of atrial NP (ANP) and brain NP (BNP) in different types of AF and whether ANP and BNP have predictive values for relapsed AF have not been determined. Purpose: We aimed to examine the levels of ANP and BNP in AF to determine their roles in different types...

Foreign body ingestion is a frequent presentation in pediatric population. However lack of a standardized protocol and varying approaches often lead to divergent outcomes in emergent cases. Presenting acutely, it is a source of significant patient and family distress as well as a variety of serious complications.

متن کاملMortality analysis in hip fracture patients: implications for design of future outcome trials.
INTRODUCTION Patients with hip fractures are usually frail and elderly with a 30-day mortality in excess of 10% in European series. Perioperative morbidity is often multifactorial in nature, and unimodal interventions will not necessarily decrease mortality. The purpose of this prospective study was to analyse causes of mortality, and thereby the potential and limitations to decrease mortality ...
