Table 3 A comparative data of the operation time, lymphatic duct signal-to-background ratio (SBR), and lymph node SBR on canine mammary tumors with varying concentrations of indocyanine green (ICG). The study included three distinct concentration groups: 0.5 mg/ml (n = 10), 1.0 mg/ml (n = 18), and 2.5 mg/ml (n = 10). The results are presented as mean values and standard deviations, accompanied by their respective 95% confidence intervals for each ICG concentration. Statistically significant differences (p < 0.05, one-way ANOVA with Tukey’s post hoc test) are indicated by different superscripts within a row.
