  1. Data were first tested for normality. The Kolmogorov–Smirnov test was used to test whether a single sample was from a particular distribution, then this single-sample Kolmogorov–Smirnov test checked the normality of the data. A test level of α = 0.05 and P < 0.05 indicate that a sample does not fit a normal distribution.LDH, lactic dehydrogenase.
  2. The continuity variables of normal distributions are described by the mean (s.d.) and the continuity variables of non-normal distributions by the median and quartiles.
