Provider fees vary based on means of compensation from fixed salary to hourly wages.
The sample size (number of animals per treatment) chosen is based on means and variances from similar experiments with the KRN arthritis mouse model and afforded detection of 20% differences between experimental groups with a statistical power of 0.80 assuming a 2-sided alpha of <0.05.
Calculations of construct and discriminative validity were based on mean scores from the first test occasion.
The longitudinal model by Samtani is derived based on mean data from various different phase II trials.
Efficacy analysis of outcome variables was based on mean changes from baseline to endpoint in the ITT population.
For multi-phase tests (training, cued fear test), rate changes were calculated as suppression ratios based on mean values from the relevant test phases (pre/(pre+post)).
The age-specific serving sizes were based on mean values from weighted foods recorded during four 1-week periods 3 4 months apart by randomly selected women from the cohort (Wolk A, unpublished data).
In Table 3, each cell represents a separate logistic regression model on the relation between accessibility to each type of food outlet (defined based on mean distance from participants' residence), as well as tertiles of WRFEI and odds of obesity.
We calculated the sample size by using the nQuery Advisor program, Release 6.0, 2005 (Statistical Solutions, Boston, MA, USA), based on mean change from baseline of our previous study 22 of a score of 1.9 with 5% type I error and 20% type II error, so the sample size of each group would be 180.
We used age-specific (<53, 53 65, ⩾66 years) portion sizes that were based on mean values obtained from 213 randomly chosen women from the study area whose food intake for 5922 days was weighed and recorded (A Wolk, unpublished data).
