BACKGROUND N-methyl-d-aspartate receptor (NMDAR) antibodies have been documented in the serum of individuals with primary psychiatric disorders from several independent cohorts, but these findings have not been systematically assessed in aggregate or in relation to methodological covariates. METHODS We searched MEDLINE, EMBASE, and PsycINFO for studies in any language that provided data on NM...
BACKGROUND International guidelines recommend that the decision threshold for troponin should be the 99th percentile of a normal population, or, if the laboratory assay is not sufficiently precise at this low level, the level at which the assay achieves a 10% or better coefficient of variation (CV). Our objectives were to examine US hospital laboratory troponin reports to determine whether eith...
The South Asian summer monsoon brings copious rain to agriculture-dependent country India and bulk of the precipitation in central is attributed low pressure systems (LPS). Large uncertainty exists statistics LPS during historical period future projections. In this study, we have developed an tracking approach which considers geopotential height anomaly relative vorticity thresholds. validated ...
OBJECTIVE The purpose of this study was to analyze humeral length (HL) in a normal population and to compare that with HL in a population of fetuses with trisomy 21 to determine the most efficient discriminating parameters for diagnostic accuracy. METHODS A nested case-control study comparing HLs from a normal population and a population of fetuses with trisomy 21 was conducted. Humeral lengt...
BACKGROUND Although aerobic fitness has been well studied, establishing developmental patterns from previous studies has some limitations including selection bias and the statistical modeling of growth-related data. PURPOSE The purpose of this study was to develop age-, gender-, and race-specific smoothed percentiles for aerobic fitness using the LMS (L=skewness, M=median, and S=coefficient o...
Mechanisms underlying the binocular combination of visual information were investigated within the context of a visual information acquisition theory proposed by Loftus, Busey, and their colleagues (e.g., as described by T.A. Busey & G. R. Loftus, 1994). A central assumption of the theory is that of a sensory threshold, which engenders an information loss such that information processing subseq...
Abnormal passenger behavior in rail transit has become a top priority, as it affects operational safety. Passenger travel time is the main basis for identifying abnormal while considering flexibility of time. Currently, method to use absolute threshold discrimination based on distribution However, there problem missing due large difference between Origin-Destinations (ODs). Therefore, this pape...
