Best evidence topic reports (BETs) summarise the evidence pertaining to particular clinical questions. They are not systematic reviews, but rather contain the best (highest level) evidence that can be practically obtained by busy practising clinicians. The search strategies used to find the best evidence are reported in detail in order to allow clinicians to update searches whenever necessary. The BETs published below were first reported at the Critical Appraisal Journal Club at the Manchester Royal Infirmary1 or placed on the BestBETs web site. Each BET has been constructed in the four stages that have been described elsewhere.2 The BETs shown here together with those published previously and those currently under construction can be seen at http://www.bestbets.org.3 Six BETs are included in this issue of the journal.
Biphasic or monophasic defibrillation for adult ventricular fibrillation
Ascorbate for alkali burns to the eye
Leucovorin (calcium folinate) in “antifreeze” poisoning
Vasopressin or adrenaline (epinephrine) in cardiac resuscitation
Is the central venous pressure reading equally reliable if the central line is inserted via the femoral vein
Oucher or CHEOPS for pain assessment in children
