  1. Data were expressed as a mean (standard deviation (SD)). A greater water contact angle means a more hydrophobic surface. Oxinium had the smallest water contact angle, indicating the most hydrophilic surface.
  2. a P < 0.01 compared with Oxinium.
  3. b P < 0.01 compared with Co-Cr-Mo.
  4. c P < 0.01 compared with Ti-6Al-4 V.
  5. d P < 0.01 compared with Cp-Ti.
  6. e P < 0.01 compared with SUS316L.
