Dunnett's Multiple Comparison Test for cell viability between different TiO₂ groups. T test was preformed for 2B and 3B. Significance level is indicated by*.

Dunnett's Multiple Comparison Test	Mean diff.	q	Significance P < 0.05 (t-test)	Summary	95% CI of diff
1A vs 2A	−4.897	1.677	No	ns	−12.96 to 3.167
1A vs 3A	−10.79	3.693	Yes	**	−18.85 to −2.721
1A vs 1B	−14.26	4.882	Yes	***	−22.32 to −6.191
1A vs 2B	−19.43	6.653	0.0156	***	−27.49 to −11.36
1A vs 3B	−28.86	9.881	0.0147	***	−36.92 to −20.79

*B2 vs B3: Unpaired t test: shows that there is a significant increase in viability in 3B compared to 2B with a P value of 0.0330.
