LIMITATIONS
The limitations of this study include:
- Inability to be registered with systematic review databases such as
PROSPERO
- Due to rapidly evolving data, figures quoted are those written at the
time of constructing this manuscript
- Grey literature and clinical trials couldn’t be added because of
scarcity of data
- Technical reports and perspective reports couldn’t undergo risk bias
assessment and hence qualitative reporting was done.
- The guidelines were not evaluated because of the exhaustive process
and time constraints
