The major driving forces of dengue outbreaks and the exposure–response relationships. a The association between the mean temperature of the wettest quarter (Bio8) and local transmission of dengue; b The association between the mean temperature of the driest quarter (Bio9) and local transmission of dengue; c The association between the precipitation seasonality (Bio15) and local transmission of dengue; d The association between NDVI in March (NDVI3) and local transmission of dengue; e The association between NDVI in July (NDVI7) and local transmission of dengue; f The association between the annual mean imported cases at log scale and local transmission of dengue. The reference values on the exposure–response relationships were the average levels of the cities without dengue outbreaks (OR = 1), representing the relative risk-free points. The shadow areas show 95% confidence intervals
