Systematic reviews and meta-analyses are becoming increasingly important in informing clinical practice and commissioning. Two systematic reviews of a treatment for low back pain and sciatica using epidural steroid injections, published in the same year, arrived at conflicting conclusions. Only one was reported in a digest for evidence-based medicine. ⋯ Estimation of summary odds ratios in one review led to stronger conclusions about effectiveness. In conclusion, the choice of methods for systematic review may alter views about the current state of evidence. Users should be aware that systematic reviews include an element of judgement, whatever method is used.

General practitioners (GPs) need to be aware of the risk factors for suicide. GP records may provide clues to identifying the relative importance of such risk factors. ⋯ Females at risk of suicide are more likely than males to have been diagnosed and treated for mental illness. It is likely that GPs are under-diagnosed and under-treating males at risk. Data from the GPRD give comparable results to those from other studies. The GPRD is a potentially useful tool for research into relatively uncommon events in general practice.

So far, no-one has attempted to evaluate the overall balance of serious, but not necessarily fatal, disease among a cohort of oral contraceptive users. ⋯ Past users of older, higher dose oral contraceptives can be reassured that the small increased risk of serious disease seen during current use does not persist after stopping, and that latent effects do not appear later in life. Currently available oral contraceptives, containing less than 50 micrograms of oestrogen accompanied by the progestogen, levonorgestrel, or norethisterone acetate, do not appear to be associated with an increased net risk of serious disease.
