Kruskal-Wallis test P values for the associations of each spline growth parameter between the growth clusters “poor,” “average,” and “good” determined for L. monocytogenes strains (n = 388) at 9.0% NaCl. Significant associations are indicated with an asterisk. μ corresponds to growth rate (OD600 U/h), λ to lag time (h), MaxOD to maximum growth (OD600 units), and AUC to the area under curve calculated by an integral.
