1IQR: interquartile range. Pulmonary extension was usually classified by five degrees of severity according to the French Society of Thoracic Imaging recommendations by grading lung involvement as absent or minimal (<10%), moderate (<25%), extensive (25–50%), severe (50–75%), and critical (>75%) (8). Because of the low number of hemodialysis patients with severe pulmonary injuries, extensive, severe, and critical involvement were gathered into one (>25%). Normal values.
