background: the purpose of this study was to present a scientific reason for pressure ulcer risk scales: cubbin& jackson modified braden, norton, and waterlow, as a nursing diagnosis tool by utilizing predictive validity of pressure sores. methods: articles published between 1966 and 2013 from periodicals indexed in the ovid medline, embase, cinahl, koreamed, ndsl, and other databases were sele...

Summary receiver operating characteristics (sROC) analysis is a recently developed statistical technique that can be applied to meta-analysis of diagnostic tests. This technique can overcome some of the limitations associated with pooling the sensitivities and specificities of published studies. The sROC curve is initially constructed by plotting the sensitivity (true positivity) and false posi...

Objective: the present meta-analysis was designed to determine the value of Pediatric Emergency Care Applied Research Network (PECARN) rule in prediction of clinically important traumatic brain injury (ciTBI).Methods: Extensive search was conducted in the databases of Medline, Embase, Scopus, Web of Sciences, Cinahl up to the end of August 2017. The search records were screened and summarized b...

The summary receiver operating characteristic (SROC) curve has been recommended to represent the performance of a diagnostic test, based on data from a meta-analysis. However, little is known about the basic properties of the SROC curve or its estimate. In this paper, the position of the SROC curve is characterized in terms of the overall diagnostic odds ratio and the magnitude of inter-study h...

Our goal in this study is to find risk factors associated with Pressure Ulcers (PUs) and to develop predictive models of PU incidence. We focus on Intensive Care Unit (ICU) patients since patients admitted to ICU have shown higher incidence of PUs. The most common PU incidence assessment tool is the Braden scale, which sums up six subscale features. In an ICU setting it's known drawbacks includ...

The aim of this study was to evaluate the predictive validity of the Braden Scale for Predicting Pressure Sore Risk in elderly residents of long-term care facilities (LTCFs) in Brazil. The determination of the cutoff score for the Brazilian population is important for the comparison between Brazilian and international studies and establishment of guidelines for prevention of pressure ulcers in ...

BACKGROUND The aim of this study was to systematically evaluate the diagnostic performance of nCD64 for neonatal sepsis. METHODS Computer retrieval was conducted for the databases of PubMed, Embase, and Springer databases up to March 18, 2015 to select the relevant studies on nCD64 and neonatal sepsis. Sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR),...

BackgroundTo assess the diagnostic accuracy of Mayo Clinic echocardiographic criteria to differentiate constrictive pericarditis (CP) and restrictive cardiomyopathy (RCM).MethodsWe searched electronic databases from inception July 1, 2022. The index tests were criteria. We performed a bivariate random-effects model estimate pooled sensitivity specificity with their 95% confidence interval (CI)....

BACKGROUND Because of the high malignant degree of pancreatic cancer (PC), the early diagnosis of PC is of great concern. Macrophage inhibitory cytokine-1 (MIC-1) was reported to be a potential diagnostic biomarker, but its diagnostic value is indeterminate. Therefore, we performed this meta-analysis to compare it to carbohydrate antigen 19-9 (CA19-9), the most frequently used serum biomarker i...

Abstract Background Recent researches have suggested that long noncoding RNA (lncRNA) is involved in the tumorigenesis and development of stomach cancer (SC). This meta-analysis aimed to identify diagnostic performance circulating lncRNAs SC. Methods All relevant studies were systematically searched through PubMed, Web Science, Cochrane Library, EMBASE databases. The values mainly assessed by p...
