Table 1. Baseline clinical characteristics of patients treated with acute appendicitis.
-Continuous variables are reported as median (interquartile range).
-Mann-Whitney U-test was used to compare continuous variables between groups.
-Percentages are reported to one decimal place.
-p-values reported to three decimal places (statistical significance in bold).
CT: computerised tomography; USS: ultrasound scan; AA: acute appendicitis; WCC: White cell count; CRP: c-reactive protein.
