Box plots with quantiles and outliers comparing the Σ_mol, R (left), cloud radius (middle), and cloud area (A_R; right) distributions of cross-matched PAHs at 30 pc physical resolution and CO clouds at 90 pc in a subsample of 27 galaxies. The colored boxes represent the PAH cloud property distributions without overlapping clouds. The black boxes represent the property distributions of the cross-matched CO clouds. The dashed and dotted horizontal lines represent the median property of the full sample of CO clouds and PAH clouds, respectively.
