Title:

2019: A systematic examination for Global Burden of Disease

Reviewer's report:
I confirm that the analysis of data presented in this paper is of great interest and
the correlation with socio-economic conditions of the different countries, already
proposed and non satisfactorily improved in the present revision, 
can be
posponed to a subsequent paper. Therefore I recommend acceptance of the
paper. 
Nevertheless, I think that language must be improved: in page 5 line 6 (and in
abstract) why "has played" and not "plays"?
page 5 line 59 "Africa and nations a not re well narrated" ??
Page 10 line 11 CRC accounted for ... please correct the figures for incident
cases, deaths. Similarly in line 16
Page 21 line 36 sigmoid copy ???
