Comparison of histologic markers of middle ear inflammation when transtympanic prednisolone (Pred) or aldosterone (Aldo) were given three (+ 3h) or six (+ 6h) hours after inoculation with H flu compared to no-treatment controls.

ANOVA compared all five treatment groups for each measure and the respective F ratio and probability are listed for each quantitative measure. All for quantitative measures showed a difference among the treatments groups so Post-Hoc tests were run to determine the statistical differences between the individual steroid treatment groups and H flu only controls. Those statistically significant are in bold.
