Data extraction and management
Two review authors will extract data from eligible studies independently
using a data extraction sheet; we will settle any differences
in opinion through discussion. A third review author will be
consulted if a consensus cannot be reached. Specifically, we will
extract the following information:
• Authors; title; year of publication.
• Country of study; setting of study (e.g. primary care).
• Characteristics of participants.
• Number of participants with new pressure ulcers; stage of
new pressure ulcers.
• Inclusion criteria and exclusion criteria for participants.
• Number of participants randomised to each trial arm;
method of randomisation; allocation concealment; blinding of
participants and trial personnel.
• Setting of treatment.
