Table 4 The chi-squared test of skin and mucosal reactions

From: Side effects of CT-guided implantation of 125I seeds for recurrent malignant tumors of the head and neck assisted by 3D printing non co-planar template

  Chi square P
Skin reaction
 D2cc (<  30 vs. ≥30 Gy) 4.1 0.091
 D0.1cc (<  60 vs. ≥60 Gy) 10.1 0.011
 Previous accumulative dose (< 60 vs. ≥60 Gy) 0.94 0.54
Mucosal reaction
 D2cc (< 30 vs. ≥30 Gy) 0.68 0.41
 D0.1cc (< 60 vs. ≥60 Gy) 3.8 0.2
 Previous accumulative dose (< 60 vs. ≥60 Gy) 0.94 0.54
  1. D2cc: the dose to 2 cc volume, D0.1cc: the dose to 0.2cc volume
