Spleen weight, age and PMI of punching fails and mechanically compared groups

The samples that could not be punched and, therefore, not mechanically tested were not significantly different from the tested samples in regard to spleen weight (Mann-Whitney U-test; U = 246, p = 0.101), age at death (Welch’s test; t(50.29) = 1.33, p = 0.189) and PMI (Welch’s test; t(29.84) = 0.01, p = 0.992). Spleen samples with histological signs of inflammation had a significantly higher PMI compared to samples without signs of inflammation (Welch’s test; t(15.82) = 3.68, p = 0.002). The female age at death was significantly lower compared to the male age at death (Welch’s test; t(22.12) = 2.40, p = 0.026). The samples with mild microscopic signs of fibrosis were significantly lighter when compared to the samples with severe signs of fibrosis (Mann-Whitney U-test; U = 21, p = 0.024).

Pediatric cases

An overview of the measured rheological properties of the four pediatric cases as well as the age at death, the cause of death, spleen weight, sex and PMI is given in Table 3.

Age[y] | COD | Spleen weight [g] | Sex | PMI[h] | G’[Pa] | G’’[Pa] | G*[Pa]
0.02 | Heart failure | 10 | f | 63 | 1453 | 338 | 1491
2 | Sepsis | 41 | m | 64 | 2171 | 451 | 2217
5 | TBI | 64 | m | 112 | 1366 | 443 | 1436
6 | Polytrauma | 99 | m | 108 | 1771 | 890 | 1982
