Systematic Reviews and Meta-analysis in Rhinosinusitis: a Critical Review of the Reviews

Abstract

Purpose of Review

There has been an explosion in the number of published systematic reviews on chronic rhinosinusitis in the last decade.

Recent Findings

While the aim of these reviews in facilitating evidence-based practice is laudable, poor quality reviews may contain significant bias that can mislead a non-discerning reader.

Summary

Attention therefore must be given to review methodology before implanting findings. Organisations such as the Cochrane Collaboration promote high-quality reviews, but are limited in chronic sinus disease by heterogeneous outcomes and a paucity of randomised trials.
