BACKGROUND Proteinuria is one of the essential criteria for the clinical diagnosis of pre-eclampsia. Increasing levels of proteinuria is considered to be associated with adverse maternal and fetal outcomes. We aim to determine the accuracy with which the amount of proteinuria predicts maternal and fetal complications in women with pre-eclampsia by systematic quantitative review of test accuracy...

Stimulus generalization is often regarded as a fundamental component of category learning, yet it has not been directly studied in this context. Here we develop a technique for measuring generalization based on sequential effects in subjects’ responses. We find that patterns of generalization can adapt to global properties of the task, but only when the category structure is defined by perceptu...

Hausfater and colleagues stated that in febrile adult patients presenting to the emergency department (ED) a procalcitonin (PCT) ≥0.2 mcg/l can help physicians to identify bacterial/parasitic infections [1]. We disagree and want to illustrate that by calculating likelihood ratios (LR). A LR is a semi-quantitative measure of the performance of a diagnostic test, expressing the magnitude by which...

background: the superiority of either of body mass index (bmi), waist circumference (wc), waist-to-hip ratio (whr) and waist-to-height ratio (whtr) for prediction of metabolic syndrome (mets) is remained controversial in asian population. the objective of this study was to compare the discriminative capacity of either of these measures in prediction of non-adipose components of mets. methods: i...
