Approximately 0.5 g of dust (median) was analyzed by GC/MS in selected ion monitoring mode after Soxhlet extraction using 6% diethyl ether in hexane, concentration to 2.5 mL, florisil column cleaning, and final concentration to 2 mL in 1% ether.
Because variables had nonparametric distributions, medians were analyzed.
Differences in medians were analyzed using the Wilcoxon rank-sum test or the Kruskal-Wallis test, and differences in group proportions were assessed using a χ2 test or Fisher's exact test as appropriate.
The steady-state median diameters were analyzed.
Otherwise, the median values were analyzed for significant difference using Mann-Whitney test.
Participants' median RTs were analyzed with a mixed 2 (cue number) × 2 (object switch condition) ANOVA.
Median RTs were analyzed with a 2 (Alerting Signal) × 2 (Orienting Cue) × 2 (Congruent/Incongruent) × 2 (Group) mixed ANOVA.
AData for antimicrobial susceptible isolates are not shown When median MICs were analyzed for all agents the following changes were identified as in Table 2.
Due to the large variation among bacterial CFU numbers in each group, the median scores were analyzed by nonparametric statistical methods which showed similar results as well.
