Migration rates of cells treated with Brazilian red propolis. a Line graph showing migration rates of treated and untreated cells using different concentrations of Brazilian red propolis at various time points. Values are expressed as mean migration rate ± standard error as indicated by the error bars. Significance: *p-value < 0.05 treatment vs control. b Polynomial trend line showing the concentration-dependent trend of the migration rate of cells treated with Brazilian red propolis over 24 h. Values are expressed as mean migration rate ± standard error as indicated by the error bars
