↵a Multivariate logistic regression.
↵b QIs with incomplete records of explanatory variables excluded: three participants had incomplete severity information; two had incomplete length of diagnosis; eight had no Lower Super Output Area deprivation score.
↵c Age entered in regression analysis as continuous measure and then odds ratio converted from a difference of 1 to 10 years, thus the presented odds ratios represents a difference of 10 years at any point on the age scale. OA = osteoarthritis.
