The medical records of the patients hospitalized at Ospedali Riuniti of Bergamo were reviewed at the end of the study by a single neurologist, skilled in stroke management and blinded to the questionnaires. Sensitivity and specificity, in addition to positive and negative predictive values, of single questions versus final diagnosis were assessed. Logistic regression analysis was also performed to identify those questions useful to suspect strokes. We collected 143 valid questionnaires, related to 63 men and 80 women, aged 34-99 years (mean, 71.8 years). The question concerning headache had the lowest sensitivity and specificity, respectively 57.1% and 36.5%, and the question concerning leg palsy had the highest sensitivity and specificity, respectively 82.0% and 52.4%.
