• Means followed by distinct capital letters (A-B) represent statistically significant differences in each column (Baseline thermocycled specimen comparisons for each group) (P < .05).
• Means followed by distinct small letters (a-b) represent statistically significant differences in each row (P < .05).
• Means followed by distinct numbers (1-2) represent statistically significant differences between baseline value comparisons of groups in each column (P < .05).
• Means followed by distinct small letters (x-y) represent statistically significant differences between thermocycled values comparisons of groups in each column (P < .05).
