Age
Patients under the age of 30 had a higher SCHNOS-C pre-operatively
(76.7, compared to 63.9 in over 30s) but also showed a greater
post-operative improvement (scoring 25.7 compared to 35)
(p<0.001, 95% CI [32.9-69.1]). The over 30s population
had a poorer post-operative improvement by comparison (p=0.79, 95% CI
[0.0-62.6]). SCHNOS-O improved from 74.5 to 30 (under
30s)(p<0.001, 95% CI [31.3-57.7]) compared to 88.3 to
45.8 (over 30s)(p=0.058, 95% CI [0.0-86.9]) respectively. Figure 4.
