| Study group (topical + oral HA) | Control group (topical HA) | P value | |
|---|---|---|---|
| Number of patients | 24 | 30 | |
| Age | 48.6 ± 13.0 | 53.29 ± 10.8 | 0.073 |
| Gender (% female) | 75 | 76 | 0.755 |
| Schirmer test (mm/5 min) | 4.5 ± 1.0 | 4.9 ± 1.9 | 0.486 |
| TBUT (sec) | 3.3 ± 1.1 | 3.8 ± 1.5 | 0.104 |
| CSF (Oxford score) | 1.8 ± 1.0 | 1.5 ± 0.6 | 0.445 |
