Table 4.

Viability of 3T3-L1 cells cultivated in the direct contact with the coatings and in their extracts in DMEM/F12 media for 48 h, Me(Q₁ – Q₃).

Groups, n = 3	Percentage of viable cells, %
	Direct contact method	Extract method
Cells without coating, control group	100	100
Cells with CP-2 coating	86.2 (83.7–95.4)	117.9 (107.9–131.4)
Cells with Sr-Si-CP coating	108.1 (104.7–117.2)	112.9 (107.7–118.9)

Note: The results are presented as the median (Me) characterizing values in 50% of samples, Q₁ – 25% percentile and Q₃ – 75% percentile. Differences compared with the controls by Mann-Whitney U–test were considered significant at p < 0.05, n – the number of tested specimens.
