Abstract

This is the protocol for a review and there is no abstract. The objectives are as follows:

To summarise the characteristics and synthesise the results of empirical studies that have (i) investigated the prevalence of selective inclusion or reporting in systematic reviews of RCTs, (ii) investigated the factors associated with this (e.g. statistical significance or direction of effect), and (iii) quantified the bias.
