Table 5

Correlations. The table shows the correlation coefficients, all of which were statistically significant between the variations in questionnaire values and UCVA, BCVA, and CS values, which were 0.548, 0.508, and 0.409, respectively. This result demonstrates a direct and positive association between the items evaluated.

Field correlated with the questionnaire	Correlation	value
UCVA	0.548^γ	0.005
BCVA	0.508^δ	0.009
CS	0.409^γ	0.033

UCVA = uncorrected visual acuity; BCVA = best-corrected visual acuity; CS = contrast sensitivity.
γ = Pearson’s correlation coefficient; δ = Spearman’s correlation coefficient.
