Our goal was to describe this relationship of biochemical markers with small-for-gestational-age fetuses in our population. MATERIAL AND METHODS Retrospective analytic study of 2 035 pregnant women that underwent first-trimester screening in t...
OBJECTIVES To describe changes over time in extent of idiopathic pulmonary fibrosis (IPF) at multidetector computed tomography (MDCT) assessed by semi-quantitative visual scores (VSs) and fully automatic histogram-based quantitative evaluation and to test the relationship between these two methods of quantification. METHODS Forty IPF patients (median age: 70 y, interquartile: 62-75 years; M:F...

Resampling nonparametric with return method, where each sample poin...
BACKGROUND Upper arm postures are believed to be an important risk determinant for musculoskeletal disorder development in the neck and shoulders. The 10th and 90th percentiles of the angular elevation distribution have been reported in many studies as measures of neutral and extreme postural exposures, and variation has been quantified by the 10th-90th percentile range. Further, the 50th perce...
