Key parameters of OECD biodegradation screening tests were analyzed for impact on the assessment of biodegradation potential of selected fragrance compounds.
The results of the tests were analyzed for both, the static and the dynamic phases of the sliding and were interpreted based on the static initial friction angle, ϕ0, and the limit friction angle, ϕlim.
Data that failed the normality test were analyzed for differences between groups using the Mann–Whitney rank sum test; P ≤ 0.01 was considered significant.
After 24 h incubation, cells under the various conditions tested were analyzed for cell viability by Trypan blue exclusion and light microscopy.
Data of the written tests were analyzed for changes between pre- and post-tests as well as post-test 1 and 2 within the groups of users and non-users using unpaired student's t-test.
The different liver tests (ALT, alkaline phosphatase, γ-GT, bilirubin, albumin, prothrombin time, serum bile acids, galactose elimination capacity and aminopyrine breath test were analyzed for their potential to recognize stage in the major diagnostic groups reported in table 1.
To demonstrate the differences between the event groups (no event, chronic event and acute event), Chi-Square tests were analyzed for differences in categorical baseline characteristics and incidence of events between the groups.
The scores from the pre and post tests were analyzed for difference in performance using appropriate statistics for hypothesis testing namely; paired t test (to assess if there was significant difference in means of performances) and correlation coefficients (Pearson product moment).
The independent-samples t-test was analyzed for cell and animal experiments (mean ± SD).
A minimal amount of 35 μg of cellular DNA per test was analyzed for the only sample with a ratio >2, unsuccessfully, which could have limited our ability to sequence HPV-human DNA junctions.
