Table 6 indicates comparison of ammonia and TCD including Vp, Vm, Vd, PI, and RI between group A and B before and after treatment. t1 and P1 represent comparison before and after treatment in group A; t2 and P2 represent comparison before and after treatment in group B. Group A is the control group; group B is the treated group. Continuous data were compared using t-test. P < 0.05 means significant differences in an index before and after treatment.
