Because I'm not.
Doing a stats research project, and I have to show the between groups point estimate and 95% CI.
Shouldn't be hard, but the study I was assigned doesn't have them set up the way I'm used to seeing them. The charts are only comparing within groups, so I went to the results text and read, but am still only seeing the experimental group talked about. My teacher agreed, but said: for the poster summary table then, the p-values for the Group x Test interaction are the ones indicating the significant or lack of significant difference between groups for each outcome measure. From the means they provide, you can calculate the mean difference between dance and control group and it also allows you to indicate the direction of this difference.
I get what he's saying.... I'm just not seeing where to find that. Here's a copy of one of the pages that should have this in there- if someone can just give me an example or something of what he wants, I'd greatly appreciate it.

Directions During Performance of the Sharpened-Romberg Stance, M ± SD
Dance training, on the other hand, induced significant postural-sway and trunk-kinematic changes in the performance of the OL test (Table 2). A significant Group Test interaction for COPmax and COPSD in the M/L direction, COPmax F(1, 24) = 5.21, p < .05, COPSD F(1, 24) = 5.72, p < .05, suggests that adaptations were specific to the DG. Particularly, post hoc analysis confirmed that after prac- tice, the DG significantly reduced COPmax from 8.592 to 5.087 cm (p < .05) and COPSD from 1.73 to 1.33 cm (p < .05) in the M/L direction. No significant changes were noted for the CG. COPmax and COPSD were also reduced in the A/P direction, but these reductions only approached significance, COPmax F(1, 24) = 4.48, p = .045, COPSD F(1, 24) = 3.013, p = .095. Post hoc analysis did not statistically verify the amplitude of these changes.
A significant Group Test interaction for trunk angular displacement in the roll plane, TRmax F(1, 24) = 6.21, p < .05, TRSD F(1, 24) = 4.62, p < .05, confirmed the effect of dance practice on both peak-to-peak amplitude and SD of trunk rota- tion during performance of the OL stance. Post hoc pre–post training comparisons showed that the DG significantly (p < .05) decreased peak-to-peak amplitude of trunk-roll rotation from 9.032° to 4.598° and SD of trunk rotation from 2.093° to 1.131° (p < .05) as a result of dance practice. A similar tendency toward decreased trunk rotation was noted in the pitch direction, but this reduction was not con- firmed by a significant Group Test interaction for either peak-to-peak amplitude or SD of pitch trunk rotation (Table 2).
