- Abbreviations: GM Geometric mean; SD Standard Deviation
- Cluster 1: Low concentration of endotoxin and low dust allergens. Cluster 2: High endotoxin clustering with pet allergens (Cat and Dog) and Alternaria. Cluster 3: High endotoxin clustering with Aspergillus, Dust Mites, Mouse and Rat, and Cockroach Allergens,
- Blue shading indicates endotoxin or allergen concentration significantly lower than the population average. Orange shading indicates endotoxin or allergen concentration significantly higher than the population average. P-value for significance < 0.05
