Table 2 Comparison of the incidence rates and average areas of skin sensory disturbances between the two groups (n = 30)
Indicator | Control group | Experimental group | Statistical value | P value |
|---|---|---|---|---|
Incidence rate of skin sensory disturbances [n (%)] | 26.7% (8/30) | 6.7% (2/30) | χ2 = 4.32 | 0.038 |
Average area of sensory disturbances (\(\overline{{\text{x}}}\) ± s, cm2) | 12.23 ± 2.51 cm2 | 5.95 ± 1.28 cm2 | t = 3.33 | 0.010 |
