Bonferroni-adjusted multiple comparisons ( Table S5 ) did not reveal statistically significant pairwise differences ( p > 0.05), although near-significant trends of cell viability were observed between C and SC (mean difference = −0.019, p = 0.065, 95% CI [−0.0389, 0.0009]), and between SC and N2 (mean difference = 0.018, p = 0.089, 95% CI [0.019, 0.0379]).
Although variants treated with AgNPs exhibited an increasing trend in total phenol content relative to the control, N1, N2, and N3 did not differ from control (adjusted p ≥ 0.37), and their CIs include zero.
The highest mean difference in chlorophyll a content was observed between control (C) and SC ( p > 0.46 in all comparisons), but it did not reach statistical significance.
Although the ANOVA confirmed significant group-level differences, most Bonferroni pairwise comparisons failed to reach significance, reflecting the conservative nature of this correction.
