receiver operating characteristics (roc) curves have numerous applications for identifying a cut-off point in diagnostic tests. nonetheless, given that sometimes two cut-off points have to be specified simultaneously, the roc curve can be used to identify such points. the volume under the roc surface (vus) serves as a criterion for the accuracy of diagnostic tests. one of the unfortunate outcom...
سابقه و هدف: فیبروز کبدی نتیجه محتوم بیماری های مزمن کبدی می باشدکه سر انجام به سمت سیروز پیشرفت می کنند. ارزیابی حضور و شدت فیبروز کبدی در بیماران با بیماری مزمن کبدی اهمیت زیادی در تعیین استراتژی درمان، پاسخ به درمان، پروگنوز و ریسک فاکتورهای بالقوه جهت بروز عوارض بیماری دارد. تاکنون بیوپسی کبد بهترین روش ارزیابی فیبروز کبد شناخته شده است ولی از آن جایی که روشی تهاجمی همراه با عوارض زیادی برا...
nuclear level densities and spin cut-off factors have been deduced for nuclei in the mass region 24‹a‹63,from a microscopic theory, which includes nuclear pairing interaction. single particle levels for both seeger and nilsson potentials were used in the calcdations. level densities extracted from the theory are compared with their conesponding experimental values, it is found that the overall ...
BACKGROUND The brief Patient Health Questionnaire (PHQ-9) is commonly used to screen for depression with 10 often recommended as the cut-off score. We summarized the psychometric properties of the PHQ-9 across a range of studies and cut-off scores to select the optimal cut-off for detecting depression. METHODS We searched Embase, MEDLINE and PsycINFO from 1999 to August 2010 for studies that ...
BACKGROUND The tuberculin skin test (TST) is the standard tool to diagnose latent tuberculosis infection (LTBI) in mass screening. The aim of this study is to find an optimal cut-off point of the TST+ rate within tuberculosis (TB) contacts to predict the active TB development among adolescents in school TB outbreaks. METHODS The Korean National Health Insurance Review and Assessment database ...
Background: Introduction: Searching for an ideal marker for diagnosing neonatal infection is still an important concern in every country. There are many biomarkers reported for neonatal sepsis. Haptoglobin is an acute phase reactants which rise in response to infection and injuries. In this report we discussed the efficacy of serum haptoglobin level in different cut off levels in early onset ne...
INTRODUCTION We hypothesized a relationship between severity of thoracic aortic atheroma (AA) and prevalence of high-risk coronary anatomy (HRCA). MATERIAL AND METHODS We investigated AA diagnosed by transesophageal echocardiography and HRCA diagnosed by coronary angiography in 187 patients. HRCA was defined as ≥ 50% stenosis of the left main coronary artery or significant 3-vessel coronary a...
زمینه و هدف: سرطان آندومتر شایعترین بدخیمی دستگاه ژنیتال در زنان می باشد. استفاده از روش های تشخیصی غیرتهاجمی مانند اندازه گیری بیومارکرهای سرمی ca125 و he4 در صورتی که دقت تشخیص خوبی داشته باشند می توانند در فاز پیش از آغاز درمان جهت برنامه ریزی مناسب درمان برای بیمار به کار روند. روش بررسی: در یک مطالعه مقطعی (cross-sectional) 68 بیمار که در فاصله زمانی بین آبان 91 تا آبان 93 با نمونه پاتولوژ...
Considering water scarcity in Iran, application of deficit irrigation or water stress on some crops is inevitable. We need to provide appropriate design for deficit irrigation. Furrow irrigation management to obtain high efficiency and uniformity is difficult. Therefore, to investigate the variation of the input discharge, the cut-off time and furrow length that are effective on the efficiency ...
Background & Objective: Preterm labor is a major risk factor of mortality and morbidity in newborns and fetuses. Low birth weight is also a risk factor for mortality and various neonatal diseases. This study aimed to determine the association between the CRP levels in first trimester of pregnancy with low birth weight and preterm labor. Methods & Materials: In this prospective cohort study, ...
