Data Extraction and Management
Two independent reviewers (ZY and GXH) screened the titles and abstracts
for potentially eligible studies identified by the primary search, and
then reviewed the full texts to evaluate their final eligibility. The
two authors cross-checked each other’s articles, and, in the case of any
disagreement regarding extracted data, a third author (LY) was brought
into the discussion. Decisions were made based on consensus.
After selecting articles for inclusion, we extracted the following data
along with the intervention characteristics: first author, publication
year, publication country, sample size, average patient age,
intervention duration, intervention group, control group, follow-up
time, outcomes.
