OBJECTIVE To assess whether crude league tables of mortality and league tables of risk adjusted mortality accurately reflect the performance of hospitals. DESIGN Longitudinal study of mortality occurring in hospital. SETTING 9 neonatal intensive care units in the United Kingdom. SUBJECTS 2671 very low birth weight or preterm infants admitted to neonatal intensive care units between 1988 a...

tions to virology, enzymology, nucleic acid chemistry, and studies of intermolecular binding. The text is very readable. Detail is confined primarily to the many useful tables, phase diagrams, and experimental examples which make this volume an excellent reference. Theory is kept to a minimum sufficient to guide the reader in the intelligent selection of phase systems to meet particular purific...

BACKGROUND Centrifugation (Cf) is a common method of fat processing but may be time consuming, especially when processing large volumes. OBJECTIVES To determine the effects on fat grafting time, volume efficiency, reoperations, and complication rates of Cf vs an autologous fat processing system (Rv) that incorporates fat harvesting and processing in a single unit. METHODS We performed a ret...

BACKGROUND AND PURPOSE Perfusion-weighted (PW) MRI is increasingly used to identify the tissue at risk. The adequate PW-MRI map and threshold remain controversial due to a considerable individual variation of values. By comparative positron emission tomography, we evaluated a simple MR-based and positron emission tomography-validated calibration of PW maps. METHODS PW-MRI and quantitative pos...

The longstanding problem of automatic table interpretation still illudes us. Its solution would not only be an aid to table processing applications such as large volume table conversion, but would also be an aid in solving related problems such as information extraction, semantic annotation, and semi-structured data management. In this paper, we offer a solution for the common special case in w...
