| Variable | MVD (Mean (SEM)) | p Value* | Ki‐67 expression | ||||
|---|---|---|---|---|---|---|---|
| S1 | S2 | S3 | S4 | p Value† | |||
| Leptin | 0.040 | 0.790 | |||||
| − | 45.06 (21.16) | 5 | 0 | 1 | 0 | ||
| + | 44.00 (19.61) | 10 | 6 | 3 | 2 | ||

MVD, microvessel density; S1, ⩽25% positive cells; S2, 26–50% positive cells; S3, 51–75% positive cells; S4, ⩾75% positive cells;−, negative; +, weak; ++, moderate; +++, strong.
