Sentence examples for trials were calculated using from inspiring English sources

Average spectrograms for the odor-sampling intervals of correct and incorrect trials were calculated using a multi-taper method from the Chronux open source MATLAB toolbox (available at: http://chronux.org/) (Mitra and Bokil, 2008).

Sample sizes required for future clinical trials were calculated using annualized change score in 3 potential outcome measures: whole brain atrophy (using BBSI), change in graded naming test, and DTI change within either right paracallosal cingulum or right uncinate fasciculus (chosen on the basis of statistical significance).

Estimation of sample sizes for future trials were calculated (using Stata) with 80% power and 5% 2-tailed significance using the mean difference in the rate of change between groups for each DTI metric and neuropsychological score, and whole brain atrophy, using the BBSI, to detect a 20, 30, 40, and 50% reduction in yearly change.

(2) O D = ∑ k = 1 p O D k p To compare actual rat data with values that would arise from a completely ideal route ("ideal" in purely distance terms, assuming no distinction between vertical and horizontal), optimal paths for each trial were calculated using the same start positions and the same fixed retrieval positions as in the experiment itself.

A percent PPI score for each trial was calculated using the following equation: %PPI = 100*(ASRstartle pulse alone - ASRprepulse+startle pulse)/ASRstartle pulse alone (see [14] for greater details).
