Descriptive statistics for selected variables measured in cats with polytrauma at the hospital presentation (n = 38); cats were classified as survivors (n = 24) and non-survivors (n = 14).

Values for each analyte are presented as median and (range). ATTS, Animal Trauma Triage Score; APPLE, feline Acute Patient Physiologic and Laboratory Evaluation; HCT, hematocrit value; ICU, intensive care unit; ODs, organ dysfunctions; PT, prothrombin time; aPTT, thromboplastin activity time; NA, not applicable; R.I., reference interval. P-value <0.05 indicates a significant difference between survivors and non-survivors.
