Note. Data presented as numerical means with the range in brackets below. Statistical differences (p < 0.05) were determined using the log transformed means (geometrical means, GM). Means (within columns) with the same lowercase letter in bold are indicative of a significantly difference (p < 0.05) between the respective groups. n = sample size.
