Summary:Table 1 Categories of evidence 185 Level Type of evidence Ia Evidence obtained from meta-analysis of randomised controlled trials Ib Evidence obtained from at least one randomised controlled trial IIa Evidence obtained from at least one well designed controlled study without randomisation IIb Evidence obtained from at least one other type of well designed quasi-experimental study III Evidence obtained from well designed non-experimental descriptive studies such as comparative studies, correlation studies, and case controlled studies IV Evidence obtained from expert committee reports and/or clinical experiences of respected authorities Table 2 Grading of recommendations Grade Type of recommendations A (levels Ia, Ib) Requires at least one randomised controlled trial as part of a body of literature of overall good quality and consistency addressing the specific recommendation B (levels IIa, IIb, III) Requires availability of well conducted clinical studies but no randomised clinical trials on the topic of recommendation C (level IV) Requires evidence from expert committee reports or opinions and/or clinical experience of respected authorities. Because it does not cross the pleura, pneumothorax is much less common than in percutaneous biopsy.
