Thirty-one observers (five radiologists, five radiology residents, and 21 nonradiologists) examined low-contrast images of 13 polyvinylchloride cylinders. Image density ranged from 1.91 to 2.05 OD units with a background density of 2.09 OD units. The experiment tested visual performance under various clinically relevant lighting conditions by asking the(More)
INTRODUCTION Retinal nerve fiber layer (RNFL) thinning, assessed by optical coherence tomography (OCT), has recently been reported in various dementias. METHODS We conducted a systematic review and meta-analysis to investigate the diagnostic utility of RNFL thickness measurement using OCT in dementia (including Alzheimer's disease [AD] and mild cognitive(More)

Parents of preschoolers in a health management organization completed a temperament questionnaire, received written parenting information tailored to their child's temperament, and were(More)
IASI data has been extensively assimilated in Numerical Weather Prediction (NWP) systems, with significant positive forecast impact. NWP systems have also been used to monitor and further investigate the data, contributing to a detailed characterisation of the performance of the instrument. Here we present a specific analysis that points to a very small(More)
