Table 4 Comparison of the new score and clinical diagnostics

From: A new adult appendicitis score improves diagnostic accuracy of acute appendicitis - a prospective study

Assessment of appendicitis Sensitivity (%) Specificity (%) p-value for sensitivity* p-value for specificity**
At clinical examination 54.8 86.1 0.363 0.002
At 6 h from clinical examination 55.4 86.6 0.529 0.007
Within the first 24 hours 98.5 78.4 <0.001 <0.001
Score > =16 58.0 92.7   
  1. *Comparison with sensitivity of the new score > =16 (McNemar test).
  2. **Comparison with specificity of the new score > =16 (McNemar test).
  3. High probability of appendicitis based on clinical examination alone.
  4. Clinical diagnosis of appendicitis within 6 h from clinical examination.
