Change of serum β-hCG in 48 hours according to the degree of angiogenesis by VEGF evaluated. Values ​ ​expressed as mean percentage of variation (%) with standard deviations (SD), minimum, and maximum values​ ​.

VEGF	𝑁 (𝑛=18)	Mean variation of 𝛽-hCG at 48 h (%) ± SD (min–max)
I	6	−18.35±24.49 (−56.87–8.42)
II	5	+32.95±27.70 (2.26–77.50)
III	7	+37.55±58.79 (−12.68–118.80)
