Table 2. Results of generalized linear regression analyses on detrended infectious disease outbreaks in relation to detrended monthly values of the NAO (North Atlantic Oscillation) (from NAO1: January to NAO12: December) of each year or with one year lag. Best models were selected using a backward-stepwise procedure using AIC and Bonferroni corrections, with only significant, or close to significant (p < 0.08) explicative variables indicated.
