Predicted Guillain-Barré syndrome (GBS) background incidence with its 95 % confidence limits; monthly incidence of GBS among the population under surveillance as observed by the neurologist network during the period 2009–2010, seasonal and A(H1N1)pdm09 influenza vaccination campaigns (in the latter case with monthly number of doses for the whole population from 16 November 2009 to 1 February 2010, and routine campaign intervals —marked between vertical green lines—for seasonal immunisations), clinical antecedents (black arrows) and clinical onset of GBS patients (red arrows) immunised during the 42-day prior to clinical onset; and monthly incidence of GBS during the surveillance period, as seen from country-wide diagnostic data on 2383 hospital-admitted patients over 20 years and having GBS coded as ICD-9-CM 357.0 as their principal diagnosis at discharge (Discharge Certificates, National In-Patient Hospital Registry)
