 Odds ratios* (change in probability of treatment use when moving from deprivation group to one immediately more deprived) of radiotherapy and surgery in men with prostate cancer, with analysis restricted (stratified) by diagnosis period, stage, age, and morphology

*All odds ratios relate to logistic regression models adjusted for age, diagnosis era, deprivation, morphology, and stage (when available). Values denote proportion change in odds ratio for one level ordinal increase in deprivation group (for example, from 2nd to 3rd least deprived group).
