Correlation between standardized death rate for area and LA(50).
In order to investigate the relationship between standardized death rate for area and 50% mortality rate for burn area (LA(50)), correlation analysis, curve estimation and linear regression were performed with the variables. The results showed that: (1) there was a similarity in sort order of standardized death rate in control groups of samples, compared with the experimental group; (2) there were significant differences between the sort order from low to high mortality rate of standardized death rate in control groups for burn area, compared with the sort order in the experimental group; (3) there was a similarity (P<0.05) in low to high sort order for standardized death rate compared with high to low sort order for LA(50) in the experimental group; and (4) there was an extraordinarily significant correlation (P<0.0001) between linear regression analysis and curve estimation for the standardized death rate and LA(50) using a Pearson correlation. The observation that there was a significant relation between the sort orders in standardized death rate and LA(50) shows that the standardized death rate for area can reflect accurately mortality in each of samples.
