Overall, there was limited variation between practices for guideline adherences according to structure indicators of care; the IQR of the total structure score was 4 to 5 (p = 1.00).> -wrap-foot> *Differences between practices, tested in hierarchical regression model, without other independent factors.
The small standard deviations in the absorption parameters demonstrate limited variation in absorption between individuals and in comparison with previous 25(OH)D3 absorption studies (Table 2).
Previous studies have shown limited variation in depression prevalence between countries, but it is unlikely that wide differences would exist between neighbouring Northern European countries such as Sweden and Norway [ 19].
These findings are based on comparisons between siblings that limit variation to short-lived shocks and controls for unobserved differences between mothers that could bias estimates.
Ideally, there should be limited variation in the use of Read codes between family practices.
The results indicate that the maximum deviation rule limits the variation between sound insulation and indices in a very efficient way.
In the study design, we have tried to limit the variation between the two techniques further by performing same-day measurements within 1 to 2 h.
This study is also limited by variation between different sets of clinical guidelines, which means that it may not be appropriate to apply a single standard.
Equipment ill-suited for clinical practice has been used [ 7, 18] or the number of study subjects has been small, limiting the between-subject variation [ 6, 14, 16, 17].
The performance of the T3 and T4 assays we reported (Gilbert and Sui 2008) fall well within the manufacturer's recommended limits, and variation between replicate samples was typically < 3%.
Since we have previously shown that Schwann cells are sensitive to dietary changes [17], all animals were subjected to 14 h fasting and to a subsequent 6 h refeeding before sacrifice in order to limit the metabolic variation between individuals.
