Figure legends
Figure 1: Distribution of tracheal mucus scores among horses with normal bronchoalveolar lavage (BAL) cytology, with mild-moderate equine asthma (MEA) diagnosis, based on reference values >10% neutrophils, >5% mast cells or eosinophils, and severe equine asthma (SEA) with reference values >25% neutrophils. Significant differences were found between all groups.
Figure 2: The distribution of horses with normal BAL cytology, mild-moderate equine asthma (MEA) and severe equine asthma (SEA) sub-divided into horses stabled in individual boxes and horses in loose-housing systems.
Table 1: Horses included in the study, sub-divided into groups based on owner complaints (coughing, poor performance). For each group, age and bronchoalveolar lavage (BAL) cytology results are shown, cytological diagnoses are based on reference values for mild-moderate equine asthma >10% neutrophils, >5% mast cells or eosinophils, and SEA >25% neutrophils.
