Criteria for considering studies for this review
Types of studies
We will include all published and unpublished randomised controlled
trials evaluating the efficacy of any psychosocial and educational
interventions for women in the latent phase of labour.
Studies published in abstract form will only be included if the
abstract contained sufficient information to assess eligibility and
risk of bias, and if the results are described in detail. We plan to
include cluster-randomised trials if they are eligible. We will not
include quasi-randomised trials.
