D1 : Scope & purpose, D2: Stakeholder involvement, D3: Rigor of involvement, D4: Clarity of presentation, D5: Applicability, D6: editorial independence.All the 23 items of the AGREE-II instrument are rated on a 7-point scale where a score of 1 is given when there is no information that is relevant to the item or if the concept is very poorly reported; a score of 7 is given if the quality of reporting is exceptional and where the full criteria and considerations articulated in the AGREE-II User's Manual have been met; and a score between 2 and 6 is assigned when the reporting of the AGREE II item does not meet the full criteria or considerations. Scores increase as more criteria are met and considerations addressed. In other words, the higher the score, the better the quality of the CPG item.SOA: South Africa; IND: India; POL: Poland; MAL: Malaysia; EUR: Europe; JAP: Japan; LAT: Latin America; AUS: Australia; CAN: Canada; SAU: Saudi Arabia and NICE: UK's National Institute for Health and Clinical Excellence).*Although the scoring is done in integers, the numbers in this column represent the averages of the scoring done by 4 assessors.**Risk of bias: +++ high, ++ intermediate, + low.***This is based on the subjective assessment made individually by each of the 4 assessors in response to: “Do you recommend this CPG for use?”
