Table 3 Disease specific reporting precision according to disease of the case examples. Reference variable: Salmonellosis case examples; outcome variable: reporting precision (n= 5995)

From: Reliability of case definitions for public health surveillance assessed by Round-Robin test methodology

Disease Odds Ratio * Confidence Interval
Salmonellosis - -
Tuberculosis 0.678 0.477 – 0.965
Measles 0.375 0.277 – 0.509
Hepatitis C 0.277 0.208 – 0.368
Pathogenic E. coli enteritis 0.229 0.173 – 0.304
Adenovirus conjunctivitis 0.173 0.130 – 0.230
Haemorrhagic fever 0.161 0.123 – 0.210
Meningococcal meningitis 0.153 0.117 – 0.201
EHEC (enterohaemorrhagic E. coli) 0.099 0.076 – 0.129
Influenza 0.093 0.071 – 0.121
Hepatitis B 0.057 0.043 – 0.075
Creutzfeldt-Jakob-Disease (CJD) 0.012 0.008 – 0.017
Polio 0.008 0.005 – 0.013
  1. + The higher the odds ratio the higher the agreement with the gold standard. E.g. the chance of agreement with the gold standard was only two third (OR = 0.678) for tuberculosis case examples compared to Salmonella case examples.
  2. * The four salmonella-like examples consisted in 2 examples of Salmonella enterica, one example of Salmonella Paratyphi and one example of an enteric disease with unidentified pathogen.
  3. ** The four EHEC-like case examples consisted in four causes by EHEC and one cause by Shigella.
