Comparison of D₅₀ droplet diameters between Endosurf device groups. Bar graph comparing the median D₅₀ values of aerosol droplet diameters generated by Endosurf devices grouped by performance: High D₅₀ group (devices 4, 5, 6, 7) and Low D₅₀ group (devices 8, 9, 10, 11, 12). The Mann–Whitney U test showed a statistically significant reduction in droplet size in the Low D₅₀ group (*p = 0.0159). Error bars represent standard deviations.
