Dear Dr Charulatha Banerjee,
This is indeed a very important paper. It does shows clearly that children with a low MUAC have a high risk of death in Indian children as well. This is consistent with previous studies from Bangladesh which showed similar results (1) (2) (3).
It is not clear to me why in the discussion the authors recommend to use when possible WHZ in addition to MUAC. The article does not present data to support this point. As a reminder, a previous study suggested it is more appropriate to use MUAC with a higher cut off than adding WHZ when the objective is to detect most effectively children with a high risk of death (4).
