Left eye macula descriptive data, ANOVA post hoc results, and η2 effect size for boxers and controls
| Retinal sector | Boxers T2, mean (SE) n=16 | Control T2, mean (SE) n=20 | F-test statistic, two-tailed significance, and η2 effect size |
|---|---|---|---|

| Average thickness | 275.8 (3.2) | 297.8 (12.3)b | F (1, 34) =2.40, P>0.05, η2=0.06 |
| Total volume | 7.77 (0.1) | 8.0 (0.1) | F (1, 34) =4.42, P<0.05, η2=0.11a |
Notes:
a
Small to medium effect size.
b
One participant’s data excluded due to outlier. A measurement of 529.6 for average thickness in the control group skewed the data to generate a large standard error of 12.3.
