2.2 Process of study selection
The study was conceptualised by JJM. The article screening process was
performed in a cyclical manner to make the process more robust. In phase
one SG and BS conducted the web search jointly with mutual
consultations. Any dispute was resolved on the basis of a mutually
acceptable consensus. The inclusion and exclusion criteria were devised
by JJM & KKG. Once the whole study selection process was completed, the
team performed the same search in reverse order, with JJM & KKG doing
the web-based screening and BS & SG formulating the selection criteria.
