Table 3.
Multinomial logistic regression model showing relative risk of number of chronic pain sites in participants with 0, 1, 2–3 and ≥4 long-term conditions. Model 1: adjusted for age, sex, Townsend score (deprivation). Model 2: Model 1 + smoking, alcohol, BMI and physical activity levels. All p-values were two sided and <0.01.
