    Snippet: Statistical calculations were performed using IBM SPSS Statistics version 22.0.0.0 (IBM Corporation). Incidence was calculated with the average population of 2008 and 2009 derived from publically available official data (Statistics Iceland, http:// www.hagstofa.is/Hagtolur/Mannfjoldi). Categorical data were compared using χ 2 and Fisher's exact test as appropriate. Continuous data were compared with 95% confidence intervals (CIs). Risk factors w.....
    Document: Statistical calculations were performed using IBM SPSS Statistics version 22.0.0.0 (IBM Corporation). Incidence was calculated with the average population of 2008 and 2009 derived from publically available official data (Statistics Iceland, http:// www.hagstofa.is/Hagtolur/Mannfjoldi). Categorical data were compared using χ 2 and Fisher's exact test as appropriate. Continuous data were compared with 95% confidence intervals (CIs). Risk factors were examined in conjunction with specific etiologic results (S pneumoniae, M pneumoniae, and influenza) with direct comparison, as detailed above, as well as multinomial logistic regression. Variables that were included in the analysis were age, sex, any underlying disease, asthma, chronic obstructive pulmonary disease, ischemic heart disease, heart failure, diabetes mellitus type 2, underlying neurologic disease, chronic renal failure, malignancy, smoking status, recent use of antimicrobials, influenza vaccination, pneumococcal vaccination, fever, cough, purulent cough, hemoptysis, pleuritic chest pain, sweating, dyspnea, stomach pain, and diarrhea.
