Study selection and inclusion criteria
Articles reporting early and late outcomes for MI and MS procedures were included. Studies were excluded from the analysis if: data was in a non-extractable format; data was duplicated; or the research was performed in an animal model. Two assessors (M.M., M.R.) independently reviewed the titles and abstracts of potentially eligible studies and selected studies that met the inclusion/exclusion criteria for full-text retrieval and further examination. Any disagreement was resolved by discussion with a third author (M.G.). Inter-rater agreement was assessed using Cohen’s κ coefficient.
