Transverse scans from head to toe measured absorption of x-ray beams at two different energy levels allowing for a valid determination of lean body mass, fat mass and fat percentage (Lukaski, 1993).
The aim of this study was to determine the extent to which differences between Pakistani and white British women in gestational glucose levels mediate differences in cord-blood leptin levels (a valid proxy for birth fat mass that has been used in previous studies for this purpose [ 7, 10, 26, 27]).
Rather than betting the farm on a single technology, all are showcasing their efforts with diesel, hybrids, plug-in electric vehicles and even biofuels all of which have a valid shot at becoming the mass-market answer for reducing emissions and lessening dependence on oil.
First, we select a signal peak from a mass spectrum and a valid charge state z.
25 On the basis of these facts, we believe DXR MCI to be a valid surrogate measure of hand bone mass.
Many patients did not have a valid recent record for smoking, body mass index, or alcohol intake so we excluded these confounders from the main analyses but carried out secondary analyses to assess the potential impact of these on the results.
