Figure 4.

The frequency of cases with (A) the blue pattern and (B) the red pattern in each group divided according to rapidity of death. Rapidly indicates rapidly fatal cases; presumed rapidly, presumed rapidly fatal cases; rapidly & presumed rapidly, combination of rapidly and presumed rapidly fatal cases; non-rapidly, non-rapidly fatal cases; HS, hemorrhagic shock cases; <12 y, cases under 12 years of age; black box, positive cases; white box, negative cases. (A) The blue pattern did not significantly differ in appearance frequency across the categories. (B) Compared to non-rapidly fatal cases, the red pattern appeared with higher frequency in the rapidly and/or presumed rapidly cases, especially excluding hemorrhagic shock cases and those under 12 years of age (P < 0.05, #P < 0.01 vs. non-rapidly fatal death; χ2 contingency test).
