Mosaic plots of the FEV₁% dynamic classes.

<p>Mosaic plots were used to assess positive or negative associations between clinical phenotypes and FEV₁ dynamic classes with other categorical variables. Since width and length of the boxes are proportional to the observed frequencies in the datasets, the area of the boxes represent the proportion of subjects that share the attributes. To the extent that the observed proportions of subjects differs from expected proportions, the boxes are shaded to different levels of Pearson residuals. The associations between FEV₁% Dynamic Class with MDCPs and gender in the CF cohort are shown (A). The associations between FEV₁% Dynamic Class, COPD GOLD grades and either MMRC dyspnea scores or pulmonary exacerbations are depicted (B,C).
