The risk of dying increases with warmer temperature, aging, and their interaction. Forest plots show how temperature, aging, and their interaction influence the risk of dying in naïve mosquitoes (A), injured mosquitoes (B), E. coli-infected mosquitoes (C), and M. luteus-infected mosquitoes (D). Circles indicate the hazard ratio and lines mark the 95% confidence interval. Hazards greater than 1.0 indicate a greater risk of death. Data were analyzed by Cox nonproportional hazards
