Table 1.
Variable (Baseline value) | Unstandardized coefficient (B) | Standardized coefficient (β) | P value |
---|---|---|---|
Meibum expressibility | −18.2 | −0.396 | 0.003 |
TBUT | 4.5 | 0.453 | 0.007 |
Sex (female) | −19.1 | −0.396 | 0.019 |
The change in the OSDI score is defined as the OSDI after the 3rd treatment session – the OSDI at baseline. Age (P = 0.950), meibum quality (P = 0.980), lid margin abnormality (P = 0.928), and ocular surface staining (P = 0.767) were excluded from the model by using the stepwise method.
P value for the overall model is 0.002 and adjusted R2 is 0.368.
OSDI = Ocular Surface Disease Index; TBUT = tear film break-up time.
