I have a dataset containing binary variable DIAGNOSIS (0 & 1 for control and case) and the range of AGE is from 20 ~ 80. I'm interested to see the distribution (# of cases & controls) in various age groups with an interval of 10 years. (20~30, 30~40, 50~60, 60~70, etc). 

 

Please suggest to me how to obtain suitable tables and plots to visualize my data. 

 

PS: I have attached an example

Thanks in advance

Hello @mantubiradar19 

 

The following instructions are based on the assumptions that the data is aligned like this:

Age Diagnosis
37 0
76 1
29 0

 

Steps taken

  1. Create Age group category
    Use the Custom category feature to create age buckets.

  2. Create Cases measure:
    Use the New Calculated Item feature to calculate number cases.
    IF ( 'Diagnosis'n = 1 )
    RETURN 1
    ELSE 0
  3. Create Controls measure:
    Use the New Calculated Item feature to calculate number of controls.
    IF ( 'Diagnosis'n = 0 )
    RETURN 1
    ELSE 0

     

  4. Create Total measure:
    Use the New Calculated Item feature to calculate number of cases + controls.
    'Cases'n + 'Controls'n

     

  5. Create Cases %, Controls %, and Total %
    Use the New Calculated item feature to calculate three new aggregated measures.
    Cases %
    Sum [_ByGroup_] ('Cases'n) / Sum [_ForAll_] ('Cases'n)
    Controls %
    Sum [_ByGroup_] ('Controls'n) / Sum [_ForAll_] ('Controls'n)
    Total %
    Sum [_ByGroup_] ('Total'n) / Sum [_ForAll_] ('Total'n)

  6. Utilize Crosstab object and assign roles as below

I hope this helps.
