Odds ratios of recovery (defined as a follow-up Roland Morris score = 0) for all potential predictors in the data set: (i) unadjusted (ii) adjusted for Roland Morris baseline score. Participants presenting with baseline score of 0 excluded from analysis. (N = 217)
Variables denoted with "#" have been dichotomised from a continuous scale in relation to the relevant median.
