validity and relaibility

BACKGROUND: Ankle sprains are one of the most common musculoskeletal injuries. English and Italian versions of the Foot and Ankle Disability Index (FADI) questionnaire are available for assessment, but no Hindi version of the FADI questionnaire is yet available for the population who only communicate and understand the Hindi language. AIM: This study aims to translate and culturally adapt the Hindi version of the FADI questionnaire and to evaluate its validity. STUDY DESIGN: A Cross-Sectional Study...

BACKGROUND: Automated hearing tests have the potential to reduce the burden of disease amongst learners by introducing such services within the school context. METHODS: The aim of the study was to conduct a validation study on normal and hearing impaired learners, comparing air and bone conduction automated test results to conventional test results in 50 school aged learners (n = 100 ears) within a noise controlled school environment using a cross sectional comparative study design...

Acute appendicitis in puerperium is often diagnosed too late, because clinical signs can be unrelaible. Abdominal wall rigidity is rarely noticed in puerpeium because of weak abdominal wall muscles, laboratory parameters are not enough relaible and atip cal appendix presentation makes dificulties in diagnosis. Knowing clinical signs and symptoms of appendicitis, possible complications and their early detection, make a chanse for a good surgical outcome. Measuring of axillar and rectal temperature can take confusion in, and prolong time until surgical treatment...

BACKGROUND: Malaria shows variations in its epidemiologic pattern in relation to the local situation. Rapid diagnostic tests (RDTs) have the potential to provide an accurate diagnosis and to determine the prevalence of malaria in ureas. OBJECTIVE: The purpose of the study was to determine the prevalence of malaria and to evaluate the sensitivity and specificity of RDT for diagnosis of malaria. METHODS: A health facility based cross-sectional study was conducted from September to November 2006 among Jebrile children of less than five years of age as part of interventional study to develop and test home management of malaria in Jimma Town...

Three machine learning techniques including back propagation artificial neural network (BP-ANN), radial basis function artificial neural network (RBF-ANN) and support vector regression (SVR) were applied to predicting the peptide mobility in capillary zone electrophoresis through the development of quantitative structure-mobility relationship (QSMR) models. A data set containing 102 peptides with a large range of size, charge and hydrophobicity was used as a typical study. The optimal modeling parameters of the models were determined by grid-searching approach using 10-fold cross-validation...

PURPOSE: To evaluate the relaibility of the blood pressure measurements in an arterial hypertension study. METHODS: It was evaluated 502 nurse workers of a public hospital. After careful training and selection of the observers for the quality control at the fieldwork, it was analyzed the correlation between the 1st and 2nd measurements, final digit preference and mean systolic (SBP) and diastolic pressure (DBP). 5% of the sample had their measures compared with those checked by an expert...
