For example:
- Publication bias was avoided in the sample of studies chosen so the
results will be more representative of attachment research (1) because
unpublished studies were included which may have not been published
due to negative or inconclusive findings (1).
- The researchers could ensure reliability of the ratings of attachment was
high in the chosen studies (1) as only studies where at least one of the
authors was a reliable AAI or SSP coder were considered (1).
Look for other reasonable marking points.
