Table 1. Demographics of the study groups.
Variables | Obstructive MGD EDE | Non-obstructive MGD EDE | P |
No. of eyes | 58.3 (81) | 41.7 (58) | - |
Age, y (range) | 53 (36.5-60) | 34 (28-42.5) | ≤0.001a |
Sex | 0.115 | ||
Male | 38.3 (31) | 51.7 (30) | |
Female | 61.7 (50) | 48.3 (28) |
aIn comparisons between the non-obstructive MGD EDE and obstructive MGD EDE groups, P<0.05 indicates a statistically significant difference. For age, we used the Mann-Whitney U test. For the numbers of eyes and sex, we used the χ2 test. MGD: Meibomian gland dysfunction; EDE: Evaporative dry eye; LLT: Lipid layer thickness.
