Parameters marked as “no." display the number of positive cases in a group of patients or number of patients treated with a given medication. Other parameters are characterized by median value and interquartile range in brackets. If both groups contain the same number of cases or if they unequal by a case, then 𝑃-value is above 0.99 and is not displayed. ACE: angiotensin-converting enzyme; COPD: chronic obstructive pulmonary disease.
