Total time spent in closed and open arms. (A) We found significant differences in the total time spent in closed arms between pre- and post-intervention for the Khat (* p = 0.0122) and Khat-CA-DHK (** p = 0.0016) groups using paired t-tests. In the same panel, significant post-intervention differences in the total time spent in closed arms between the Control and Khat (* p < 0.05), Khat-CA and Khat groups (** p < 0.01), Control and Khat-CA-DHK groups (** p < 0.01), and between Khat-CA and Khat-CA-DHK groups (** p < 0.01) were identified using one-way ANOVA followed by Tukey’s test. (B) We found significant differences in the total time spent in open arms between pre- and post-intervention for the Khat (* p = 0.0492) and Khat-CA-DHK (** p = 0.0092) groups using paired t-tests. In the same panel, we did not identify significant differences in the total time spent in open arms between groups using one-way ANOVA. n = 8–9/group. Color dots represent individual data. CA, clavulanic acid; DHK, dihydrokainic acid; s, second.
