Table 1. Statistical comparison of means of percentages of fields.

Levels of significance are indicated as: ^*P<0.05, ^**P<0.01, ^***P<0.001. For instance, ^***6 h (as mentioned in the 5 min column) means that the mean of % fields in the specific Δ fraction at 5 min is statistically different from the mean of % fields in the same Δ fraction calculated at 6 h, with P<0.001. NS=not significant. Statistical analysis was performed using the two-way ANOVA with Bonferroni test.
