Table 3. Multivariate analysis of the association between patient variables and outcomes showing that primary diagnosis of non-limbal stem cell deficiency, prior bandage contact lens wear, and serum treatment remained significantly correlated with the corneal re-epithelialization.

Patient variables	Hazard ratio	95% CI	P value
Serum treatment	1.80	1.7–2.54	0.001**
Diagnosis of non-limbal stem cell deficiency	1.64	1.16–2.30	0.005**
Prior contact lens use	0.65	0.46–0.91	0.012*

The prior bandage contact lens wear was the only variable negatively correlated with corneal re-epithelialization. *P < 0.05, ** P < 0.01, CI = confidence interval.
