From: The spatiotemporal distribution of historical malaria cases in Sweden: a climatic perspective
Superposed Epoch Analysis (SEA). Results from the Superposed Epoch Analysis (SEA) for three malaria datasets (Tabellverket, Bergman, and Flensburg), assessing the response of years with the 20 most malaria-attributed deaths (Tabellverket, Bergman) and malaria cases (Flensburg) to warm-season (May–July, June–August) temperature based on all years in the 1749–1859 period. The grey-shaded area represents 95% confidence intervals derived through 1000 randomisation. The results indicate that the peak years of malaria-attributed deaths, or cases, were significantly associated with the preceding warm-season temperature. The magnitude of the climate anomalies are shown as standard deviations (SD)
