Table 4. Lesion area (mm2) across groups.
Group Mean ± SD [mm2] Range [mm2]
T1 → K+ (Control) 52.89±64.72 4.49 - 227.33
T2 → P1 (BMMSC) 6.91±7.25 0 - 19.51
T3 → P2 (BMMSC + Dienogest) 18.18±19.67 0 - 64.16
T4 → P3 (Dienogest) 23.28±16.91 0 - 53.57

Values are expressed as mean ± standard deviation (SD) and range. Lesion size was analyzed using the Kruskal–Wallis test with Bonferroni post hoc.
