Table 3

Correlations between the blink rate and other parameters.

Explanatory variables	r value	value
Men = 1; women = 0	−0.370	0.0002
Age	−0.170	0.0940
NIBUT	−0.392	<0.0001
ΔOST	−0.430	<0.0001
OST	0.004	0.9680
FVA	−0.001	0.9938
VMR	0.067	0.5126

NIBUT: noninvasive tear breakup time; FVA: functional visual acuity; VMR: visual maintenance ratio; OST: ocular surface temperature; ΔOST: difference in OST from 0 to 10 seconds without blinking.
