From: The importance of wildlife in the ecology and epidemiology of the TBE virus in Sweden: incidence of human TBE correlates with abundance of deer and hares

Meta-analysis of the effect of number of killed game animals (filled symbols) and climatic variables (open symbols) on incidences of TBE. For each entry (except the mean values) the values for six counties in Sweden were included. A positive value means that a high number of killed animals or high values of the environmental variables in one year results in increased numbers of cases of human TBE recorded the following year (i.e. a lag period of one year). The dots show the mean effect sizes, the bars the 95% confidence intervals. If the bars reach or cross the zero line it means that there was no significant effect of killed animals or environmental variables on TBE incidences. Fail-safe result: 20.4 (Orwin’s method [159]), meaning that 20.4 additional studies (in this case regions) are needed to reduce the observed mean effect size to a desired “minimal” effect size [159]. In this case the minimum effect size was set to 0.2 [160]
