Benefits and black holes in the latest Cochrane evidence

If you read my last blog, you’ll know I’ve been getting hot under the collar about evidence gaps and I’m not about to quieten down about those any time soon, as you’ll see if you read to the end of the blog. There are not just gaps but some enormous black holes, this time not because no evidence was found but because so much of it was unusable. But at least there’s good news too; some reviewers find what they’re looking for and can give us evidence which shows benefits from particular interventions. So, if you logged on thinking you’d like to read about teeth, pain (from several causes), schizophrenia treatments, gut bacteria and jellyfish (really!), you’ve come to the right place.

A mystery, missing evidence and some answers!

Contrary to what you might expect, you’ll have to wait until the end for the mystery, though in truth missing data and important questions that remain unanswered could also be labelled as that, and this is where I start.

My last blog was a round-up of new and updated reviews on asthma and I begin this one with another offering from the Cochrane Airways Group (do these people never take a day off?). It’s another tale of what we still don’t know, this time about a class of anti-inflammatory drugs called anti-leukotrines. For managing mild persistent asthma in children, low-dose inhaled corticosteroids (ICS) are recommended, but if symptoms aren’t well controlled with ICS then anti-leukotrines may be added. Almost ten years ago, a Cochrane review was published which pulled together the available evidence on the safety and effectiveness of this treatment for adults and children and found very little to go on, with just two small trials with children. Now a review has been published which looked for trials involving children (any age below 18) and finds we’re not much further on.

Waiting for the royal baby? We’ve new arrivals in the Cochrane Library

July is proving to be an exciting month here in the UK. Andy Murray is the new Wimbledon Champion, we’re enjoying lots of wonderful warm weather and we’re anticipating the arrival of the new royal baby. But before the Duke and Duchess of Cambridge have news for us, we have news for them, for these are exciting times too in the world of Cochrane and yesterday saw the publication of new evidence that delaying clamping the cord after birth benefits babies.
