Comparison of physician global assessment (PGA) score in both the groups after third and sixth laser session
| Clinical improvement | Group 1 | Group 2 | ||
|---|---|---|---|---|
| After three sessions (n = 39) | After six sessions (n = 35) | After three sessions (n = 40) | After six sessions (n = 32) | |
| No improvement | 4 (10.26%) | 0 (0.00%) | 0 (0.00%) | 0 (0.00%) |
| PGA 1 (<25% improvement) | 33 (84.62%) | 23 (65.71%) | 29 (72.50%) | 4 (12.50%) |
| PGA 2 (25%–50% improvement) | 2 (5.13%) | 10 (28.57%) | 11 (27.50%) | 19 (59.38%) |
| PGA 3 (50%–75% improvement) | 0 (0.00%) | 2 (5.71%) | 0 (0.00%) | 8 (25%) |
| PGA 4 (75% improvement) | 0 (0.00%) | 0 (0.00%) | 0 (0.00%) | 1 (3.13%) |
After third session, approximately 27% of patients in group 2 compared with 5% in group 1 had grade 2 improvement (P = 0.005). After six sessions, approximately 25% patients in group 2 versus 5% patients in group 1 had grade 3 improvement on PGA scale. Group 2 patients had higher grade of improvement than group 1 patients after six sessions of treatment (P = 0.0001)
