Reads the TWOSIDES data file, which contains adverse event data for pairs of drugs taken concurrently (N=2 interactions).
Value
A dvobject of class `TWOSIDESDB` containing the `drug_drug_interactions` data frame and associated metadata.
Details
TWOSIDES is a database of drug-drug interaction safety signals mined from the FDA's Adverse Event Reporting System using the same approach as is used to generate OffSIDES.
Database fields as follow:
- drug_1_rxnorn_id
RxNORM identifier for drug 1
- drug_1_concept_name
RxNORM name string for drug 1
- drug_2_rxnorm_id
RxNORM identifier for drug 2
- drug_2_concept_name
RxNORM name string for drug 3
- condition_meddra_id
MedDRA identifier for the side effect
- condition_concpet_name
MedDRA name string for the side effect
- A
The number of reports for the pair of drugs that report the side effect
- B
The number of reports for the pair of drugs that do not report the side effect
- C
The number of reports for other PSM matched drugs (including perhaps the single versions of drug 1 or drug 2) that report the side effect
- D
The number of reports for other PSM matched drugs and other side effects
- PRR
Proportional reporting ratio, PRR=(A/(A+B))/(C/(C+D))
- PRR_error
Error estimate of the PRR
- mean_reporting_frequency
Proportion of reports for the drug that report the side effect, A/(A+B)
