Table 1 The Centor score

From: Predicting streptococcal pharyngitis in adults in primary care: a systematic review of the diagnostic accuracy of symptoms and signs and validation of the Centor score

Symptoms Points Score Post-test probability
Tonsillar exudates 1 0 2.5%
Tender anterior cervical adenopathy 1 1 6.5%
Absence of cough 1 2 15.4%
History of fever (> 38.0°C) 1 3 31.6%
   4 55.7%
  1. Patients receive a point for the presence or absence of signs and symptoms. Each patient is assigned a score between 0 and 4 which is associated with a post-test probability as calculated by Centor and colleagues [16]. (The post-test probability values presented are the mean of the original probability intervals reported by Centor and colleagues.)
