To evaluate the diagnostic accuracy of line probe assays for drug- resistant tuberculosis (TB) in China. Chinese databases (CNKI, Wanfang, SinoMed, VIP Information) and English databases (PubMed, Emb...
Neonatal sepsis represents a major cause of morbidity and mortality in neonates. No diagnostic test has been demonstrated to be sufficiently accurate to confirm or exclude neonatal sepsis. This study ...
The aim of this study was to validate a definition to identify cases of early neonatal near miss using data from health information systems (SIS in Portuguese). This was a concurrent validation study ...
Software optical mark recognition (SOMR) is the process whereby information entered on a survey form or questionnaire is converted using specialized software into a machine-readable format. SOMR norma...
Despite major recent advances in the therapeutic management of Giant cell arteritis (GCA), the diagnosis accuracy of temporal artery ultrasound remains controversial in this disease. We performed a sy...
This study will serve as a platform to evaluate new diagnostics in children suspected to have TB, to establish diagnostic performance (sensitivity and specificity) and calculation of posit...
This study seeks to determine whether a smartphone application called CRADLE (ComputeR Assisted Detection of LEukocoria) has the potential to improve the detection of leukocoria. There wil...
This survey study purposes to determine and compare the biopsy/referral sensitivity and specificity of MelaFind to the average biopsy/referral sensitivity and specificity of dermatologists...
Sample size definition provides important information, allowing the groundwork for transparent reporting. The sample predefinition allows the trial to be large enough to be able to addres...
The overall aim of the TREND study is to improve the differential diagnosis of bacterial and viral etiology in children below 5 years of age with clinical community acquired pneumonia. Sp...
Measures for assessing the results of diagnostic and screening tests. Sensitivity represents the proportion of truly diseased persons in a screened population who are identified as being diseased by the test. It is a measure of the probability of correctly diagnosing a condition. Specificity is the proportion of truly nondiseased persons who are so identified by the screening test. It is a measure of the probability of correctly identifying a nondiseased person. (From Last, Dictionary of Epidemiology, 2d ed)
Techniques of nucleotide sequence analysis that increase the range, complexity, sensitivity, and accuracy of results by greatly increasing the scale of operations and thus the number of nucleotides, and the number of copies of each nucleotide sequenced. The sequencing may be done by analysis of the synthesis or ligation products, hybridization to preexisting sequences, etc.
Voltage-dependent cell membrane glycoproteins selectively permeable to calcium ions. They are categorized as L-, T-, N-, P-, Q-, and R-types based on the activation and inactivation kinetics, ion specificity, and sensitivity to drugs and toxins. The L- and T-types are present throughout the cardiovascular and central nervous systems and the N-, P-, Q-, & R-types are located in neuronal tissue.
Incomplete fracture of any part of a tooth, characterized by pain during mastication and sensitivity to heat, cold, sweet or sour tastes, and alcohol; it is often undiagnosed because the tooth is usually X-ray negative and normal to pulp vitality tests.
Inorganic compounds that include a positively charged tetrahedral nitrogen (ammonium ion) as part of their structure. This class of compounds includes a broad variety of simple ammonium salts and derivatives.
