Contribution to authorship
AK, FTW, MA and TU contributed equally to conceive, design and oversee
the conduct of this review. This included executing the literature
search, acquisition, analysis and interpretation of the literature. AK
critically reviewed ‘the diagnostic role’, FTW ‘the prognostic role’, MA
‘the therapeutic role’ and TU ‘intermediate-high risk group’ for the
latter two ‘role’ categories. All authors were involved in drafting the
first revision of the manuscript, critically responding to
peer-reviewer’s comments (Supplementary information 1) and producing the
amended revision that is this manuscript. We certify that all authors
are responsible for the content of this manuscript and have read and
approved of the final version. Order of authorship was decided
alphabetically.
