  1. Note: * indicates a statistically significant difference among the three time points in patients with CPACG (*P < 0.05, **P < 0.01, ***P < 0.001). Paired comparisons within groups are indicated by specific symbols: @ denotes a significant difference compared with the pre-operation value (@P < 0.05, @@P < 0.01, @@@P < 0.001); # denotes a significant difference compared with the 1-week post-operation value (#P < 0.05, ##P < 0.01, ###P < 0.001); $ denotes a significant difference compared with the 1-month post-operation value ($P < 0.05, $$P < 0.01, $$$P < 0.001).
