  1. PDDIs Potential drug-drug interactions
  2. aPercentage was calculated out of total number of patients i.e., 431
  3. bPercentage was calculated out of total number of potential drug-drug interactions i.e., 1318
  4. Overall-prevalence is the occurrence of at least one pDDI irrespective of severity type. Total number of pneumonia patients were 431. Therefore, overall-prevalence of pDDIs was 73.1% (315 out of 431)
