Note. Means and P values derived from square-root-transformed outcome variables. Means with different superscripts are statistically significantly different using Tukey-Kramer adjusted P value < .05.

As the adjusted Tukey-Kramer test is more conservative than the overall F test, the post hoc comparison of means resulted in no significant differences between means.
