Figure 1. Multiple correspondence analysis (MCA) between the early post-mortem interval and the presence of morphological changes in rats.

Figure 1

(A) MCA of the analyzed PMIs (0, 3, 6, 12 and 24 h) and the presence of internal and external morphological changes. (B) MCA of the PMIs groups I (0 and 3 h), II (6 and 12 h) and III (24 h), and the presence of internal and external morphological changes. Both plots represented the greatest cumulative variability and could capture at least the 74.2 % of the data. Abbreviations of the morphological characteristics are shown in Table 1. Dots represent each rat, while squares are the dichotomic presence of morphological changes (0: absence, 1: presence). The dashed line ellipses shown the distribution of the rats throughout the PMI.
