A:
 At least one meta-analysis, systematic review of RCTs or RCT rated as 
1++ and directly applicable to the target population or a body of 
evidence consisting principally of studies rated as 1+. directly 
applicable to the target population and with an overall consistency of 
results
          
B: A body of evidence including studies rated as 2++, 
directly applicable to the target population and with an overall 
consistency of results or extrapolated evidence from studies rated as 
1++ or 1+
          
C: A body of evidence including studies rated as 2+, 
directly applicable to the target population and with an overall 
consistency of results or extrapolated evidence from studies rated as 
2++
          
D: Evidence level 3 or 4 or extrapolated evidence from studies rated as 2+
