Limitations:
There are several limitations to our meta-analysis. The number of
articles included is low in number and quality, and the articles we
include may be potentially biased in the review process. We included
only one unpublished article, the rest were published articles, which
means there may be publication bias. Moreover, only English language
studies are included, so relevant studies published in other languages
may be missing. The literature was all retrospective, with no RCTs,
allowing for the introduction of error due to confounding and bias. In
addition, due to the insufficient number of cases, factors that cannot
be controlled consistently may have an impact, such as different types
of surgery (thoracotomy or thoracoscopy), lesion size, gender, etc., and
further evaluate whether it affects the results. For lack of long-term
prognostic indicators in the literature makes it difficult to fully
assess how age affects patient outcomes after elective CPAM resection.
