  1. mean HOOS scores (0 to 100, worst to best scale) are given in subjects prior to primary THR and at one-year follow-up (n = 95). Responsiveness is given as Spearman’s correlations of the five HOOS subscales and GPE score. Standardized effect size (SES) and standardized response mean (SRM) was calculated separately in patients who scored ‘much better’ (n = 77) and in other participants (those who scored ‘somewhat better’ and ‘better’) (n = 18). There were no subjects who scored ‘no change’, ‘somewhat worse’, ‘worse’ or ‘much worse’
