The correlation between results from different tests was calculated using the Kendall rank correlation coefficient (or Kendall's tau coefficient) computed with R software (R Development Core Team, 2010, R Foundation for Statistical Computing, Vienna, Austria. http://www.R-project.org/).org/
The concordance between the different tests is presented in supporting information Table S1 and Table S2.
Comparisons between estimates of different tests were performed with z-test.
The 95% CI between the two different tests was-4.9-5.6 allall four applied torques (3, 6 and 9 Nm and end-feel) at all three flexion angles.
The 95% CI between the two different tests was-3.4-9.9 at 6 and 9 Nm as well as end-feel, and -6.0- -2.7 at 3 Nm at all three flexion angles.
In the absence of a gold standard, comparisons between different tests have been undertaken.
A strong correlation between different test results was not observed, indicating that the standard is a set of different, generally independent stress factors.
Statistical differences between different test conditions were determined using Student's t-test.
On the other hand, the variability between different test groups was 13% smaller for the heterogenized setup (P < 0.05) as shown in Table 3.

Comparisons between different tested conditions were done with Wilcoxon non parametric paired tests for experiments described in Figures 1, 2A,B and 3. Comparisons between different tested conditions were done with Mann-Whitney unpaired non parametric test for experiments described in Figures 5A,B and 6. Figure 1 depicts the impact of the presence of FU on the incorporation of Pt into DNA.
