Dear /Sir, Madam,
my questions is, weither in systematic literature review (SLR) PICO or PECO model is compulsory to use or without these two models we can perform SLR ?
Will be highly appreciated your kind comments. Thank you
I think PICO or PECO is mendatory for SRL with Randomized Control Trial (RCT) studies
I think; it's very important to formulate your question about the case want to treat,
so it must do it, do you have another way?
According to the PRISMA statement, an explicit statement of questions being addressed with reference to participants, interventions, comparisons, outcomes and study design (PICOS) should be provided.
It indicates PICOS is mandatory for SR MA. For further information go through https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3049418/
