We searched all databases period January 1990 March 2008. Selection criteria Randomised controlled trials (RCTs), cluster RCTs associated economic evaluations, quasi-RCTs, interrupted time series analyses, before after (CBA) studies assessing enhance literacy, any language. Data collection analysis Two review authors independently selected inclusion, assessed their quality extracted data. contacted study clarification seek missing presented results as narrative tabular summary, calculated mean differences where appropriate.
