Note: Numerical data are presented as median (IQR) and proportions as numbers (%).
Abbreviations: APPLE, acute patient physiologic and laboratory evaluation; IMHA, immune‐mediated hemolytic anemia; IMHA‐IMT, immune‐mediated hemolytic anemia and thrombocytopenia; IMT, immune‐mediated thrombocytopenia.
IMHA: the APPLEfast score could be calculated for 5/7 mTPE dogs (71%) and 14/63 control dogs (22%).
IMT: the APPLEfast score could be calculated for 5/5 mTPE dogs (100%) and 11/47 control dogs (23%).
IMHA‐IMT: the APPLEfast score could be calculated for 4/5 mTPE dogs (80%) and 8/19 control dogs (42%).
