Data analysis
The evaluation of data was done by using SPSS
version 17.0 according to two-way ANOVA for
assessing variation between different time
intervals defining 5 % level of significance and
Paired samples t-test for determining variation
between the two preparations. Standard error of
means (SEM) was calculated for every mean
value.
Percent change in individual values for each
parameter, taken weekly, were computed as in
Eq 1.
% Change = {(A – B) / B}*100 ……………… (1)
where A = individual value of any parameter on
2nd, 4th, 6th, 8th, 10th and 12th week, and B =
the value of the parameter at 0 h, i.e., at
commencement of the test.
