Interpretation of data gotten from above:

Step 1: Looking at the FEV1/FVC Ratio, this means:

Step 2: Looking at the FVC, this means:

Step 3: Post-BD Response:

Step 4: If Methacholine Challenge Testing was performed, results showed:

Step 5: If Total Lung Capacity (TLC) was performed, results showed:

Step 6: If RV/TLC (pleth, Z-score) was performed, results showed:

Step 7: If Diffusion Capacity (DLCO) (%) was performed, results showed:
