Two-tailed Student's t test was used for comparison of the means between any two groups.
Comparison between any two groups was evaluated using one-way analysis of variance (ANOVA).
There was no noticeable difference found in the mean escape latency between any two groups on the first, second and third day.
With more than two types of imperfectly substitutable labor, the change in relative wages between any two groups will also depend on how each of their net demands shift relative to that of the other groups.
The Oaxaca decomposition is a technique that decomposes inequities between any two groups and has been used extensively in explaining wage differentials between males and females, immigrants and natives, blacks and whites workers.
Differences between any two groups were regarded as significant when P<0.01 or P<0.05.
Among the HA-immunized groups, there was no significant difference between any two groups (p>0.08 for all comparisons).
If the mixed models analysis showed a significant difference between groups, Fisher's LSD was used to analyse the difference between any two groups at each time point.
Kruskal-Wallis test was used for comparison between three or more groups and Mann-Whitney U test for comparisons between any two groups.
The list of the differentially expressed genes between any two groups (e.g. untreated vs. day 3, day 3 vs. resistant) was obtained using the SAM analysis, an implementation of BRB array tool [32].
Difference between any two groups was determined by analysis of variance.
