Table 5.

Results of post hoc analyses (Tukey tests) indicating the ages (in weeks) at which infant admittance magnitude (∣Y∣) pressure differences (∣Y∣ at a given static ear-canal pressure minus ∣Y∣ at TPP) were significantly different from each other (α=0.05). A blank space indicates the lack of a statistically significant difference between any of the infant groups.
