![]() ![]() In addition, other outcomes should have been considered. Some of the outcomes that the authors reported in their conclusions might not have been measured and there were limitations to the numbers and size of trials, both of which imply that the conclusions may not be reliable. One trial had no events and was not included in the meta-analysis. Some outcomes had wide confidence intervals (for example, pain). At the end of the paper, the authors' conclusion included results that were not presented in the review, for example functional recovery, operation time, and blood loss, and the conclusion from the abstract is presented above. The synthesis seems to have been appropriate. Some relevant trial details were reported, but not the gender of patients. Every year, over five million people worldwide sustain a hip fracture, resulting in the loss of at least 20.32 million disability-adjusted years of life. Efforts were made to reduce error and bias throughout the review process. Hemiarthroplasty and total hip replacement for displaced intracapsular fracture of the femoral neck have been compared and contrasted. Trial quality was assessed using suitable criteria and found to be adequate. Relevant databases were searched, but the search was not extensive for unpublished trials and only studies published in English were included some relevant trials may have been missed. The review addressed a well-defined question for study design, participants, and interventions, but the outcomes were less clear. Results for functional improvement, operation time, and blood loss were not reported. Results were reported for the subgroup analyses for these postoperative complications by length of follow-up. Overall infection rates did not significantly differ for hemiarthroplasty versus total hip arthroplasty (five trials Ι²=0). Pain was significantly more common with hemiarthroplasty versus total hip arthroplasty (RR 11.11, 95% CI 4.80 to 25.76 two trials Ι²=29%). Hemiarthroplasty had a significantly lower risk of dislocation versus total hip arthroplasty (RR 0.49, 95% CI 0.32 to 0.75 seven trials Ι²=18%). Postoperative complications: There was a significantly greater risk of reoperation for hemiarthroplasty versus total hip arthroplasty (RR 2.43, 95% CI 1.53 to 3.84 seven trials Ι²=28%). Mortality: There was no overall significant difference in mortality for hemiarthroplasty versus total hip arthroplasty (eight trials Ι²=45%) or for follow-up within one year (two trials Ι²=0), between one and five years (five trials Ι²=48%), or between five and 13 years (one trial). All trials had specified entry criteria and defined outcome measures. Five trials had adequate randomisation procedures, concealment of allocation, intention-to-treat analyses, and complete follow-up in two trials outcome assessment was blind. ![]() There were five RCTs (673 participants, range 40 to 252) and four quasi-RCTs (535 participants, range 86 to 180). Nine trials were identified, with 1,208 participants (range 40 to 252).
