this study was conducted to determine the prevalence of pe in patients with v/q scans interpreted as representing a very low probability (vlp) of pe (1-3 small segmental perfusion defects with a normal chest radiograph). an analysis of the entire data set obtained during the pioped study was performed. of the total of 1,359 patients in whom the presence or absence of pe was confirmed, 80 (6%) p...

Human immunodeficiency virus (HIV) prevention interventions, such as preexposure prophylaxis (PrEP), are often targeted to men who have sex with men (MSM) who self-report high-risk behaviors. Data from a prospective study evaluating methods to detect acute HIV infection among a primarily young (aged <25 years) and black or African American (African American) population from North Carolina were ...

According to the European Society of Cardiology guidelines, patients with chest pain requires calculation pretest probability (PTP) coronary artery disease (CAD), followed by identification diagnostic tactics. Aim. To analyze registry stable CAD in order assess frequency PTP calculation, as well validity tactics choice depending on its level. Material and methods . The data for periods from 201...

Using a pretest and posttest comparison group design, this 20 weeks study investigated the effects of a phonological awareness training program (PATP) on attention efficiency (AE) in 57 children (age = 5 to 6 years) at risk. The experimental group received the PATP (EG; n=30). We obtained pretest and posttest measures of phonological awareness and AE. The ANOVA showed significant interaction ef...

OBJECTIVES Bayesian interpretation of diagnostic test results usually involves point estimates of the pretest probability and the likelihood ratio corresponding to the test result; however, it may be more appropriate in clinical situations to consider instead a range of possible values to express uncertainty in the estimates of these parameters. We thus sought to demonstrate how uncertainty in ...

Educational psychologists find that prior knowledge influences new learning. We examined whether course achievement for introductory psychology students is facilitated or impaired by their prior knowledge of psychology. We administered a pretest exam to 422 students early in the semester and gathered subsequent exam scores and other measures of student achievement. Students generally performed ...
