The high frequency of missing placental weight in Nancy (43% of the births) compared with Poitiers (7%) led to an overrepresentation of women from Poitiers, who were less likely to smoke and were on average older compared with the original EDEN cohort (p-values for Pearson's chi-squared or Wilcoxon rank-sum test [less than or equal to]0.2; Table 1).
We found that both [C.sub.clu] and [E.sub.glob] increased significantly in all six pigeons (Figure 4; Wilcoxon rank-sum test, p < 0.001).
When assuming a non-Gaussian distribution, we used the Wilcoxon rank-sum test yielding statistical significance versus 28 days (P < .01).
Data with skewed distribution were presented as the median (Q[sub]1, Q[sub]3) and compared by the Wilcoxon rank-sum test. Comparison between skewed data and normal data was performed by the Wilcoxon rank-sum test.
We used the Mann-Whitney U test or Wilcoxon rank-sum test (Hart, 2001) which is a non-parametric alternative test to the independent sample t-test.
Total milligrams per kilogram of opioid administered over a 24-hour period were compared using Wilcoxon rank-sum test. For comparison of demographic data, mean and standard deviation were reported for continuous variables.
Wilcoxon rank-sum test was used to answer each research question.
No significant difference was detected in survival of the transferred oysters between the two locations (Wilcoxon rank-sum test, P = 0.46; Fig.
Continuous parameters were presented as mean +- standard deviation and compared using the student's t test or Wilcoxon rank-sum test, as appropriate.
Oseltamivir treatment was begun within a median 4 (IQR 2-6) days of symptom onset for survivors, compared with a median 5 (IQR 3-7) days for decedents (2-sided Wilcoxon rank-sum test; p = 0.07).
Data were not normally distributed; therefore, we used the Wilcoxon rank-sum test for all analyses (Zar, 2010).
