The comparison of correlations between selected parameters.

	Correlation coefficient	Correlation direction and degree
Skin score, temperature	−0.59	Negative, strong
Skin score, the angle of proximal interphalangeal joints	−0.52	Negative, strong
Skin score before ozonotherapy, the length of illness	+0.18	Positive, weak
The angle of proximal interphalanx joints, temperature	+0.8	Positive, strong
