Dear all,
I am using the (ssc install) charlson command to calculate the Charlson Comorbidity Index (CCI). I aim to compute each patient's CCI while applying the hierarchy of comorbidities (assign0). However, it seems that when a single patient has multiple records, the assign0 option does not assign the more mild form of a comorbidity to 0. Could I have overlooked something in the setup or usage of the command? Any advice would be greatly appreciated.
