Review Meta AnalysisSurgical versus conservative interventions for displaced intra-articular calcaneal fractures.
Fractures of the calcaneus (heel bone) comprise up to 2% of all fractures. These fractures are mostly caused by a fall from a height, and are common in younger adults. Treatment can be surgical or non-surgical; however, there is clinical uncertainty over optimal management. ⋯ The bulk of the evidence in this review derives from one large multi-centre but inadequately reported trial conducted over 15 years ago. This found no significant differences between surgical or conservative treatment in functional ability and health related quality of life at three years after displaced intra-articular calcaneal fracture. Though it reported a greater risk of major complications after surgery, subtalar arthrodeses for the development of subtalar arthritis was significantly greater after conservative treatment.Overall, there is insufficient high quality evidence relating to current practice to establish whether surgical or conservative treatment is better for adults with displaced intra-articular calcaneal fracture. Evidence from adequately powered randomised, multi-centre controlled trials, assessing patient-centred and clinically relevant outcomes is required. However, it would be prudent to reassess this need after an update of the review that incorporates new evidence from a currently ongoing multi-centre trial.

Review Meta AnalysisWITHDRAWN: Spinal manipulative therapy for low-back pain.
Low-back pain is a costly illness for which spinal manipulative therapy is commonly recommended. Previous systematic reviews and practice guidelines have reached discordant results on the effectiveness of this therapy for low-back pain. ⋯ There is no evidence that spinal manipulative therapy is superior to other standard treatments for patients with acute or chronic low-back pain.

Review Meta AnalysisPhenobarbitone versus phenytoin monotherapy for partial onset seizures and generalised onset tonic-clonic seizures.
This is an updated version of the original Cochrane review published in The Cochrane Library 2001, Issue 4.Worldwide, particularly in the developing world, phenytoin and phenobarbitone are commonly used antiepileptic drugs, primarily because they are inexpensive. The aim of this review is to summarise data from existing trials comparing phenytoin and phenobarbitone. ⋯ The results of this review show that phenobarbitone was significantly more likely to be withdrawn than phenytoin. Given that no significant differences for seizure outcomes were found, the higher withdrawal rate with phenobarbitone may be due to adverse effects. Several factors may have confounded the results of this review.

Review Meta AnalysisLevonorgestrel-releasing intrauterine device (LNG-IUD) for symptomatic endometriosis following surgery.
Various options exist for treating endometriosis, including surgical, medical, such as ovarian suppression, or a combination of these strategies. Surgical treatment of endometriosis aims to remove visible areas of endometriosis. The aim of medical therapy is to inhibit growth of endometriotic implants by induction of a hypo-estrogenic state. Treatment with a hormone-releasing intrauterine device, using levonorgestrel (LNG-IUD), has also been suggested. ⋯ There is limited but consistent evidence showing that postoperative LNG-IUD use reduces the recurrence of painful periods in women with endometriosis. Further well-designed RCTs are needed to confirm these findings.

Review Meta AnalysisVaccines for preventing pneumococcal infection in adults.
Diseases caused by Streptococcus pneumoniae (S. pneumoniae) continue to cause substantial morbidity and mortality globally. Whilst pneumococcal polysaccharide vaccines (PPVs) have the potential to prevent disease and death, the degree of protection afforded against various clinical endpoints and within different populations is uncertain. ⋯ This meta-analysis provides evidence supporting the recommendation for PPV to prevent IPD in adults. The evidence from RCTs is less clear with respect to adults with chronic illness. This might be because of lack of effect or lack of power in the studies. The meta-analysis does not provide evidence to support the routine use of PPV to prevent all-cause pneumonia or mortality.
