Group | Conventional SLT group | Subthreshold SLT group | P value∗ |
---|---|---|---|
Initial energy | 0.6 ± 0.1 | 0.4 ± 0.1 | 0.030 |
Total energy | 51.8 ± 5.7 | 37.6 ± 3.3 | 0.036 |
Data shown were presented as mean ± SD, Mann-Whitney test, n = 26. ∗ P value: subthreshold SLT group versus conventional SLT group.
