The sequence represents the ratings of the Delphi survey indicating median ratings and IQR, and appearance in the NGT ranking list, the qualitative analysis of the NGT and in the literature. Factors with no reference in the literature section were only mentioned by the experts.
DRP, drug-related problem; NGT, nominal group technique; RAAS, renin-angiotensin-aldosterone system.
