Detailed Description

This macro identifies events of interest.

• Type 2 cohort definition:
  • Event of interest: during an episode.
    
  • Find episodes with events in FupWashPer.
    
    • If FupWashPer is missing, then patients need to never have had an event.
  • Identify episodes with events in Blackoutwindow.
    
  • Identify episodes with IOC in FupWashPer at IndexDt.
    
  • Keep only valid episodes, i.e. those without events or IOC in FupWashPer.
  • Apply the EventCount parameter condition.
  • Keep only overlapping events.
  • Identify episodes with events.
    
  • Summarize events.
  • For T2CohortDef ='03', get first event in any episode.
    
• Type 3 cohort definition:
  • Event of interest: In Risk or Ctrl window.
    
  • Find all events in CTRL window.
    
    • Find all CTRL window events with prior events in LookBackLengthWin.
      
    • Find all CTRL window events with prior WASH events in LookBackLengthWin.
      
  • Find all events in RISK window.
    
    • Find all RISK window events with prior events in LookBackLengthWin.
      
    • Find all RISK window events with prior WASH events in LookBackLengthWin.
      
  • Keep only valid events (event in only one window).
    
    • Patients need to have at least one event in one of the windows.
  • Remove true duplicates.
  • For T3CohortDef ='03', get first event in any episode.
