Table: NHMRC Levels of Evidence for Intervention and Prognosis Studies

What is "all or none" under the prognosis column?

The extra definitions from the footnote of the NHMRC table have been added in to explain this. Teresa Brown, on behalf of the authors.

The quality of the evidence was assessed using the American Dietetic Association: Evidence Analysis Manual. Steps in the ADA Evidence Analysis Process [20]. This provided a quality rating of positive, neutral or negative. A summary table was developed to collate the evidence for each clinical question to be addressed (Appendix 5.3).

Could the definition of the quality ratings of positive, neutral or negative be included as a table either in this section or in appendix 5.3? (ie similiar to the NHMRC level of evidence and grade of evidence tables)

A table to explain these ratings has been added in. Teresa Brown, on behalf of the authors.
