The χ2 test was first performed as a means of assessing whether there were any significant variations in the distribution of patient population risks across the physician quartiles, and second, to evaluate whether there were any significant differences, again by physician quartiles, in the cesarean delivery rates among women for each of the risk factors.
It is therefore unlikely that there would be any significant intra-territorial variations.
Nor was there any significant variation by menopausal hormone therapy use for any physical activity in relation to ankle or wrist fracture (pinteraction = .64 and.54).54
In neither of the two PSSD studies was there any significant variation in the total volume of the CA1 stratum radiatum (Table 1), confirming the validity of the volume correction procedure used in calculating PSSD.
Despite differences in the combination of elements included, researchers were unable to find any significant variation in outcomes.
A 10 or 20 mA tetanic stimulation were well tolerated without any significant variation of the physiological data and behavioral scales.
This study was therefore designed to characterize actual transfusion practice, to determine whether there is any significant institutional practice variation and reasons why red cells are administered in critically ill patients.
An increase in the mutation rate, on the other hand, is not expected to produce any significant variation in the d N/d S ratio since increasing the rate at which mutation are introduced in populations will rise up both synonymous and nonsynonymous changes to a similar extent (Itoh et al. 2002).
Alg2, Alg3, Alg9, Alg12 (mannosyltransferase genes) and Alg6 (a glucosyltransferase gene), which are responsible for N-glycan precursor synthesis, were expressed without any significant variations.
In order to test whether there were any significant intra-group variations in the replacement values, subsets of 500 pairs of sequences were taken sequentially from start to end and also randomly from the entire dataset of a specific group of orthologs (i.e. high-/medium-/low-GC group) and 20 × 20 AARM was determined for each subset of sequence pairs.
