Table 3. The separate influence of MGX on meibomian gland dysfunction improvement.

	Beta	95% CI of Beta	p-value
BUT	2.701	(0.891,4.510)	0.003
Oxford grade	0.080	(-0.258, 0.419)	0.642
MGE	0.105	(-0.365, 0.574)	0.663
MQ	0.009	(-0.040,0.058)	0.731
OSDI	-1.352	(-14.464, 11.760)	0.840

MGX = meibomian gland expression; FU = follow-up; CI = confidence interval; BUT = tear film break up time; MGE = meibomian gland expressibility score; MQ = meibum quality score; OSDI = Ocular Surface Disease Index.

The beta and p-values were calculated using a generalized estimating equation.
