Sig

This shows the sig(netur) of the drug records summarised on ingredient level. The signetur of a prescription contains the information of when, how often, and how much of a drug a patient shall use.

DT::datatable(result$drugSig,
  rownames = FALSE
)

| Column | Description | :------------- | :------------- | ingredient_concept_id | Concept ID of ingredient. | ingredient | Name of drug ingredient. | sig | The signetur of a prescription. The sig is usually only available for prescription and often contains free text or only semi-standardised information. |
n_records | Number of records for ingredient concept. If n_records is the same as n_sample this means that there are more records but the number was cut at the pre-specified sample number for efficiency reasons. | n_sample | The pre-specified maximum sample. If n_records is smaller than the sample it means that sampling was ignored because the total number of records was already too small. | n_person | Number of individuals. | result_obscured | TRUE if count has been suppressed due to being below the minimum cell count, otherwise FALSE. |

Sig by concept

This shows the sig(netur) on the drug concept level. The signetur of a prescription contains the information of when, how often, and how much of a drug a patient shall use. The tables are identical to the overall just including two more columns at the beginning. \

| Column | Description | :------------- | :------------- | drug_concept_id | ID of the drug concept. | drug | Name of the drug concept. |
