Table 4

Partial correlation between block pressure and texture parameters.

Control variables	Partial correlation		Block pressure
Filling ratio & variation coefficient	Average diameter	Coefficient	-0.892
		Sig. (2-tailed)	0.001
Variation coefficient & average diameter	Filling ratio	Coefficient	0.271
		Sig. (2-tailed)	0.449
Average diameter & filling ratio	Variation coefficient	Coefficient	-0.856
		Sig. (2-tailed)	0.002

Correlation is significant at the 0.01 level (2-tailed).
