Mean, mean value of five animals per group; —, not applicable; n.s., no statistically significant difference. */**/*** significantly different from saline-treated negative controls: P ≤ 0.05/0.01/0.001, respectively, Dunnett’s test (left row); °/°°/°°° significantly different from Q1-treated animals: P ≤ 0.05/0.01/0.001, respectively, Student’s t-test for unpaired values, two tailed (right row). In the Q1-treated group, one animal clearly did not react to quartz treatment with increased cell counts and was thus excluded from statistical analyses with regard to coating efficiency.
