  1. <0.001* and n.s.** indicated differences of Plexin-B1 expression in normal ovaries and serous ovarian cystadenomas compared with that in serous borderline ovarian tumours and serous ovarian cystadenocarcinomas respectively.
  2. n.s.* indicated difference of Plexin-B1 expression in serous borderline ovarian tumours compared with that in serous ovarian cystadenocarcinomas.
  3. n.s. indicated differences without statistical significance.
