Table 1 Healing and non-healing rates determined by radiographic assessment at 4 weeks

From: Topical cutaneous application of CO2 accelerates bone healing in a rat femoral defect model

  Control CO2
Healing 2/11 (18.2%) 8/11 (72.7%)*
Non-healing 9/11 (81.8%) 3/11 (27.3%)
  1. Bone healing was achieved in 8 rats (72.7%) in the CO2 group, whereas the femurs of 2 rats (18.2%) showed bone healing in the control group. There was a significant difference in the bone healing rate between the two groups.* p < 0.05 compared to the control group
