American Thoracic Society/European Respiratory Society criteria and interpretative strategies were applied to the spirometric data and flow volume curves of 5 common spirometric patterns, 8 questions relating to each of the 5 patterns were posed (40 questions in total); the number of correct answers was expressed as a percentage of the total score. Boxplot: thick line in the middle is the median, the top and bottom box lines show the first and third quartiles, the box is the interquartile range, and the whiskers show the maximum and minimum values. 1Significant difference detected between medians (p < 0.01); n = 42 (as 6 participants had missing values)
