Tracheobronchoscopic examinations were performed at least 30 minutes postrace. Video recordings were scored off-site independently by two observers for EIPH and tracheal mucus accumulation (TMA). Horses with an EIPH score \u22652 were not assessed for TMA. Interobserver agreement was calculated by weighted \u03ba statistics.

Interobserver agreement was 0.73.
