The Diagnostic Adaptive Behavior Scale (DABS) was constructed with items across three domains--conceptual, social, and practical adaptive skills--and normed on a representative sample of American individuals from 4 to 21 years of age. The DABS was developed to focus its assessment around the decision point for determining the presence or absence of significant limitations of adaptive behavior f...

• The accuracy of a binary diagnostic test can easily be assessed by comparing the sensitivity and specificity with the status of respondents. When the result of a diagnostic test is continuous, the assessment of accuracy depends on a specified threshold. The receiver operating characteristic (ROC) curve, which includes all possible combinations of sensitivity and specificity, provides an appro...

background patients presenting with a mass require tissue biopsy for histological diagnosis and treatment. fine needle aspiration (fna) is offered as an atraumatic, well tolerated, and inexpensive method for obtaining a biopsy from these lesions. objectives in this study we evaluated the accuracy of fna as an atraumatic method among patients with nonthyroidal masses for diagnosis of neoplastic ...

BACKGROUND Several types of statistical methods are currently available for the meta-analysis of studies on diagnostic test accuracy. One of these methods is the Bivariate Model which involves a simultaneous analysis of the sensitivity and specificity from a set of studies. In this paper, we review the characteristics of the Bivariate Model and demonstrate how it can be extended with a discrete...

Differences in quality performance score had been reported for the routinely used diagnostic methods for malaria at different settings. There is therefore a need to evaluate the test performance of the routine diagnostic methods for malaria detection in Ho, a setting with no recorded quality evaluation on malaria diagnosis. The hospital-based cross-sectional study was conducted comprising 299 o...

A laboratory study comparing the Widal slide agglutination test using local antigens produced by Mekar Jaya Diagnostica (SAT-MJD) with imported antigens (Murex, Abbott) was carried out on 55 sera of typhoid fever patients with positive blood culture and 56 sera of non-typhoid febrile patients. The SAT-MJD antigens consisted of a mixture of 5 different phage-types of S. typhi dominantly found in...

Diagnostic testing is essential to distinguish non-diseased individuals from diseased individuals. The sensitivity and specificity are two important indices for the diagnostic accuracy of continuous-scale diagnostic tests. If we want to compare the effectiveness of two tests, it is of interest to construct a confidence interval for the difference of the two sensitivities at a fixed level of spe...

conclusions despite rapidity, automation, accuracy, cost-effectiveness, high sensitivity, and high specificity of molecular techniques, each type of molecular technology has its own advantages and disadvantages. results various types of molecular biology tools can be used to detect and quantify viral genomic elements and analyze the sequences. these molecular assays are proper technologies for ...

propose: to evaluate the specifity and sensitivity of ocular sonography in the diagnosis of retinal detachment in the presence of vitreous hemorrhage. methods: this cross-sectional study included 47 (23 right eyes and 24 left eyes) eyes of 47 patients (18 male and 29 female subjects) with vitreous hemorrhage suspected of retinal detachment requiring surgery. preoperative ocular sonography was c...
