Table 2.
Prevalence of neck problems and back problems in the 1069 individuals with idiopathic scoliosis and the 158 controls. Data is presented as number (%). The p-value shown is for the comparison between the two groups, adjusted for age (20–44 or 45 years and older), smoking, and sex. The −2 log likelihood and Nagelkerke’s R2 for the model are shown
