Application value of abdominal ultrasonography in the diagnosis of pediatric patients aged 3-12 years with acute appendicitis

Figure 1 Comparative analysis of appendix-related parameters between the two pediatric patient groups. A: The maximum diameter of the appendix of the two pediatric patient groups; B: The maximum thickness of the appendiceal wall of the two pediatric patient groups; C: The maximum extent of transmural oedema of the two pediatric patient groups. ^aP < 0.01 vs the non-acute appendicitis group; ^bP < 0.001 vs the non-acute appendicitis group.
