Study population differentiated into subgroups according to the change in visual acuity
| Gain in visual acuity | |||||
|---|---|---|---|---|---|
| >0.1 | ≤0.1 and 0.0 | p Value (1) | Visual acuity unchanged or deteriorated | pValue (2) | |
| p Value (1) = significance of the difference between the study subgroup with gain in best visual acuity of more than 0.1 and the study subgroup with gain in best visual acuity ranging between 0.1 and 0.0 . p Value (2) = significance of the difference between the study subgroup with no change in visual acuity or deterioration and the study subgroup with gain in best visual acuity > 0.10. | |||||
