* Number (n) varies because some information was missing for some patients. Values are expressed as mean with SD in parentheses, or as number of hips, with percentage in parentheses; †mean difference; ‡data collected at discharge from hospital or as close to 7 days as possible; §p value of Mann-Whitney U test; CI = confidence interval.
