dOriginal authors defined recent use and past use as first BZD claim <15 days and last BZD claim >15 days before index date, respectively. To keep homogenous with definitions of BZD use in other studies as much as possible, we redefined recent use and past use as first BZD claim <2 years and last BZD claim >2 years before index date, respectively. In this case, we pooled initial estimates to yield required estimates for “redefined" recent and past use through a random-effects model.
