In the Results section, the sentence ‘Having a methodologist as a part of a guideline team was associated with increased rate of EO recommendations per guideline (p=0.03), with using ‘lack of evidence’ as a rationale for the EO recommendations…’ should read ‘Having a methodologist as a part of a guideline team was associated with decreased rate of EO recommendations per guideline (P=0.03), with increased rate of using ‘lack of evidence’ as a rationale for the EO recommendations…’. In the Discussion section, the sentence ‘This study has also demonstrated that having a methodologist as a part of a guideline team was associated with increased rate of EO recommendations per guideline’ should read ‘This study has also demonstrated that having a methodologist as a part of a guideline team was associated with decreased rate of EO recommendations per guideline’.
