  1. Cytotoxicity evaluation: RGR: relative growth ratio; level 1: RGR = 75–99%, low cytotoxicity; level 2: RGR = 50–74%, medium cytotoxicity
  2. The evaluation standard was derived from the Biological evaluation of medical devicespart 5: test for in vitro cytotoxicity (GB/T 16886.5-2003/ISO 10993-5:1999, IDT)
