Thromboelastography (R-time) in citrated whole blood
from wild-type 129S1/Sv mJ, BALB/c, and C57BL/6 substrains. (a)
R-time (min) summarized graphically by
substrain and sex using boxplots (grey = males; white = females).
Boxplots: The lower edge of the box represents the 25th percentile
(or 1st quartile), the upper edge of the box represents the 75th
percentile (or 3rd quartile), and the line within the lower edge and
the upper edge of the box indicates the median. The distance from
the lower edge to the upper edge of the box represents the
inter-quartile range (IQR). A whisker is drawn above the 75th
percentile to the largest data value that is less or equal to the
value that is 1.5 × IQR above the 75th percentile. A whisker is
drawn below the 25th percentile to the smallest data value that is
less or equal to the value that is 1.5 × IQR below the 25th
percentile. The cross represents the arithmetic mean. Individual
measurements were added to the boxplots, where the exact horizontal
position of plotting symbols was randomly determined. (b) The median
ratio in R-time between sexes and corresponding
two-sided 95% CIs for each substrain. A two-sided 95% CI for the
ratio not containing the value 1 is equivalent to rejecting the null
hypothesis of no difference against the two-sided alternative at the
5% level of statistical significance. Two-sided 95% CIs for should
be interpreted with caution due to the small sample size per
substrain and sex.
