Figure 7. Cross-correlation function of Guillain-Barré syndrome incidence with bank vole abundance, 1973–1982. Time series are log transformed; n = 10 computable 0-order correlations. Lines represent + 2 SE. The stan-dard error is based on the assumption that the series are not cross-correlated and one of the series is white noise.
