We would like to point out that in "Additional file 2: Key reference by approach" the empty cells should say "Not applicable" instead. These references were identified for clinical questions not included in restrictive search strategies (quote: “We did not develop restrictive search strategies for clinical questions with less than two of the four PICO components, prognosis or diagnostic clinical questions identified this references”). A corrected modified file is available from the corresponding author (laura.martinez.gacia@cochrane.es).
