Normalized optical density of methicillin-resistant (MRSP) and methicillin-sensitive (MSSP) Staphylococcus pseudintermedius biofilms treated with undiluted ear cleanser products. Each box represents the interquartile range (25th to 75th percentile) with the median value indicated by the horizontal line within the box. Whiskers extend to the minimum and maximum values within 1.5 times the interquartile range. Outliers are displayed as individual dots, identified using the Tukey method. Asterisks denote treatments that are statistically significantly different from the no-treatment control (p < 0.05)
