(a, b: column comparison / x, y: row comparison). (a, b and x, y): The same letters indicate an insignificant difference among the groups (p < 0.05). The a and b letters indicate the relationships between the two lines, where measurements based on varnish variations are specified. It does not specify the relationships among the groups in terms of temperature or material differences
