Hematocytological counts are shown for all comparisons with P<.10 for both the raw and normalized cell counts. The univariate T/W method shows the P value for the two-sided paired t-test ‘T’ (‘Ln’ when a natural logarithm was applied) or Wilcoxon paired-matched signed rank (‘W’) in case normality didn’t hold. The Bonferroni and Benjamini columns show the adjusted significance levels according to the method applied. Sensitivity for outliers was investigated for the raw cell counts. See Materials & Methods for more information.
Results annotated with ‘*’ are considered significant for the method applied. Sites comparison between sampling sites; ARD average relative difference; PLT platelets; MON monocytes; BAS basophils; NGC neutrophils; LEU leukocytes; RBC red blood cells; HCT hematocrit; RD radial artery vs. dorsal hand veins; RE radial artery vs. antecubital veins; DE dorsal hand veins vs. antecubital veins; NA not applicable.
After omission of outliers the ARD for RE reduced to 3.4% and for DE to 3.7% with significances similar to before.
