This study aimed to determine valid waist circumference (WC) thresholds using receiver operating characteristic (ROC) curves for pediatric metabolic syndrome (MS) prediction and to compare validities between the thresholds derived from ROC curves and the WC cut-offs defined by International Diabetes Federation (IDF). Four hundred and sixty four males and 415 females, 10-18 years, who participat...

OBJECTIVE To explore the optimal threshold values of waist circumference (WC) in detecting the risk on cardiovascular (CV) among the Chinese children and adolescents. METHODS Association of WC and CV risk factors were studied among 65 898 children and adolescents aged 7 - 18 years whose data were pooled from nine studies carried out in China. Receive-operating characteristic analysis (ROC) an...

OBJECTIVE To estimate whether length of the first stage of labor is associated with adverse maternal and neonatal outcomes. METHODS This is a retrospective cohort study of nulliparous women with term, singleton gestations delivered in one academic center between 1990 and 2008. The length of the first stage was stratified into three subgroups: less than the 5th percentile, 5th to 95th percenti...

Multifractal detrended fluctuation analysis (DFA) can extract multi-scaling behavior and measure long-range correlations in climatic time series. In this study, with the help of multifractal DFA, we investigated scaling daily minimum/maximum temperatures during years 1989–2019 from 34 meteorological stations Bangladesh. We revealed spatial patterns, topographic impacts global warming embedded s...

OBJECTIVES We aimed to assess the differential implications of creatine kinase-myocardial band (CK-MB) and troponin measurement with the universal definition of periprocedural injury after percutaneous coronary intervention. BACKGROUND Differentiation between definitions of periprocedural necrosis and periprocedural infarction has practical, sociological, and research implications. Troponin i...

the aim of this paper is to project extreme precipitation events in an arid and a semiarid station. in order to project climate change based on general circulation models (gcms), we have applied lars-wg[1] downscaling tool. this stochastic weather generator down-scaled the climate of two synoptic stations using hadcm3 model and a2 emission scenario for 2040. we extracted extreme precipitation e...

Background Testing for prostate-specific antigen (PSA) is often recommended men with a potential risk of prostate cancer (PCa) before requiring advanced examination. However, the best PSA cutoff value remains controversial. Object We compared predictive performance age-specific percentile-based thresholds conventional >4 ng/mL PCa. Methods included who received measurements between 2003 and 201...

OBJECTIVE To derive and display the percentile score (1st-99th percentile) at each perimetric location of a standard automated perimetry test to determine whether this technique will uncover patterns of loss not visible in standard (StatPac) probability maps. METHODS We computed continuous scale probability plots of data collected from testing 305 visually healthy participants with standard a...

Abstract. Rainfall intensity–duration (ID) thresholds are commonly used to assess flash flood potential downstream of burned watersheds. High-intensity and/or long-duration rainfall is required generate floods as landscapes recover from fire, but there little guidance on how change a function time since fire. Here, we force hydrological model with radar-derived precipitation estimate ID for pos...

From a theoretical point of view, the selection thresholds is critical issue in framework Peaks Over Threshold (POT) approach, which why last decade numerous methodologies have been proposed for its selection. In this paper, we address subject from an empirical view by assessing to what extent threshold decisive quantifying market risk. For measuring risk, use Value at Risk (VaR) and Expected S...
