1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract

backgroundThe ketogenic diet is a diet high in fat but low in carbohydrate and it is suggested that this diet reduces seizure frequency. Currently, this diet is used mainly for children who continue to have seizures despite treatment with antiepileptic drugs.

objectivesTo overview the evidence from randomized controlled trials regarding the effects of ketogenic diets. SEARCH STRATEGY: We searched the Cochrane Epilepsy Group trials register (26 March 2003), the Cochrane Central Register of Controlled Trials (The Cochrane Library issue 1, 2003), MEDLINE (January 1966 to March 2003) and EMBASE (1980 to March 2003). SELECTION CRITERIA: Randomized controlled trials of ketogenic diets for people with epilepsy. DATA COLLECTION AND ANALYSIS: We planned for two reviewers to independently apply inclusion criteria and extract data. MAIN

resultsNo randomized controlled trials were found. REVIEWER'S

conclusionsThere is no reliable evidence from randomized controlled trials to support the use of ketogenic diets for people with epilepsy. There are large observational studies, some prospective, suggesting an effect on seizures. These effects need validating in randomized controlled trials. For those with a difficult epilepsy on multiple antiepileptic drugs, we consider the ketogenic diet a possible option.
