ANOVA statistics for the discrimination between the three groups: young/elderly/cataract (n = 112)
Dependent | Covariants | Right eye | Left eye | Both eyes | |||
---|---|---|---|---|---|---|---|
F | P | F | P | F | P | ||
In absence of any covariant (A and B), all tests discriminate between the groups. If visual acuity and contrast sensitivity are covariant (C), only the stray light meters and the Nyktotests and Mesotests with glare discriminate between the groups. In all comparisons, F values are highest for the CSLM and NSLM | |||||||
